So one adds R in series to mitigate device to device Rdson variation and Vth varia- tion where one turns on before the others. But one has to do analysis to see if that effect insures no device is ever over its ratings due to all changes such as initial Rdson tolerance, board layout slight R changes in traces , etc..
Note also Rdson variation with T is non linear, complicating analysis even more. The sim I showed shows this problem, but not a complete analysis as the device specs only show a typical and max Rdson value, no minimum, so the worst case is not handled, eg. Simply think of the problem as a simple voltage divider effect with load and the paralled R's, and accounting for all tolerances. Lastly note ballasting at high currents typically done with trace length versus discrete R's.
Last edited: Jul 12, So it's best to over spec the mosfet and use resistors or design the trace to accompany the mosfets. How do you work out the value of R or is it just a generic value? DarrenB said:. Nigel Goodwin said:. He's vastly overcomplicating things for you - just stick a pair of identical FET's in parallel, with heatsinks etc.
Bear in mind, you're still dissipating the same amount of heat, just spread across two FET's and heatsinks. To be honest I like to learn anyway. I think I will post the pn for the gate driver just to make sure as I don't want to buy another batch of mosfets as mousers shipping is ridiculous. Rjenkinsgbs suggestion of the TK56A12N1 seems like a good idea to be honest. Is it possible to deliver more current into the gate to achieve the same effect, I know it would be easier to change the mosfet but I wondered if it is possible to do that with a different gate driver?
Also would using 2x TK56A12N1 be silly or overkill? As I see it, spreading the load across two transistors and two heatsinks can only help. Yes you can always throw parts into a design and burn them up, thats a positive learning experience. Or take reasonable well established principles and protect in advance as the posted ap notes show from the experts. Good engineering generally does the latter. Of course you can always check the "identical" box when you order parts.
Equally important is board layout to minimize transients and timing alterations. There are ap notes on this, and books on SMPS that discuss this in detail. I have tried reading through things like this before but each and every hurdle will spur another question. The output can be either synchronous or asynchronous , depending on the programming of the third mux.
In practice, entire or parts of the adder are stored as functions into the LUTs in order to save space. Modern FPGA families expand upon the above capabilities to include higher level functionality fixed in silicon.
Having these common functions embedded in the circuit reduces the area required and gives those functions increased speed compared to building them from logical primitives. These cores exist alongside the programmable fabric, but they are built out of transistors instead of LUTs so they have ASIC-level performance and power consumption without consuming a significant amount of fabric resources, leaving more of the fabric free for the application-specific logic.
The multi-gigabit transceivers also contain high performance analog input and output circuitry along with high-speed serializers and deserializers, components which cannot be built out of LUTs.
Higher-level physical layer PHY functionality such as line coding may or may not be implemented alongside the serializers and deserializers in hard logic, depending on the FPGA. An alternate approach to using hard-macro processors is to make use of soft processor IP cores that are implemented within the FPGA logic.
Many modern FPGAs are programmed at "run time", which has led to the idea of reconfigurable computing or reconfigurable systems — CPUs that reconfigure themselves to suit the task at hand. Additionally, new, non-FPGA architectures are beginning to emerge. Software-configurable microprocessors such as the Stretch S adopt a hybrid approach by providing an array of processor cores and FPGA-like programmable cores on the same chip.
In the coarse-grained architectural approach was taken a step further by combining the logic blocks and interconnects of traditional FPGAs with embedded microprocessors and related peripherals to form a complete " system on a programmable chip ". Most of the circuitry built inside of an FPGA is synchronous circuitry that requires a clock signal.
FPGAs contain dedicated global and regional routing networks for clock and reset so they can be delivered with minimal skew. Complex designs can use multiple clocks with different frequency and phase relationships, each forming separate clock domains. These clock signals can be generated locally by an oscillator or they can be recovered from a high speed serial data stream.
Care must be taken when building clock domain crossing circuitry to avoid metastability. Xilinx's approach stacks several three or four active FPGA dies side by side on a silicon interposer — a single piece of silicon that carries passive interconnect.
The HDL form is more suited to work with large structures because it's possible to specify high-level functional behavior rather than drawing every piece by hand. However, schematic entry can allow for easier visualization of a design and its component modules. Using an electronic design automation tool, a technology-mapped netlist is generated.
The netlist can then be fit to the actual FPGA architecture using a process called place-and-route , usually performed by the FPGA company's proprietary place-and-route software.
The user will validate the map, place and route results via timing analysis , simulation , and other verification and validation methodologies. Once the design and validation process is complete, the binary file generated, typically using the FPGA vendor's proprietary software, is used to re- configure the FPGA.
However, in an attempt to reduce the complexity of designing in HDLs, which have been compared to the equivalent of assembly languages , there are moves [ by whom? Verilog was created to simplify the process making HDL more robust and flexible. Verilog is currently the most popular. Verilog creates a level of abstraction to hide away the details of its implementation. To simplify the design of complex systems in FPGAs, there exist libraries of predefined complex functions and circuits that have been tested and optimized to speed up the design process.
They are rarely free, and typically released under proprietary licenses. Other predefined circuits are available from developer communities such as OpenCores typically released under free and open source licenses such as the GPL , BSD or similar license , and other sources.
Such designs are known as " open-source hardware. In a typical design flow , an FPGA application developer will simulate the design at multiple stages throughout the design process.
Then, after the synthesis engine has mapped the design to a netlist, the netlist is translated to a gate-level description where simulation is repeated to confirm the synthesis proceeded without errors.
Finally the design is laid out in the FPGA at which point propagation delays can be added and the simulation run again with these values back-annotated onto the netlist.
These FPGAs are in-system programmable and re-programmable, but require external boot devices. In March , Tabula announced their FPGA technology that uses time-multiplexed logic and interconnect that claims potential cost savings for high-density applications. An FPGA can be used to solve any problem which is computable. Their advantage lies in that they are significantly faster for some applications because of their parallel nature and optimality in terms of the number of gates used for certain processes.
The DipTrace schematic capture module is an advanced circuit design tool that supports multi-sheet and multi-level hierarchical schematics. Circuits can be easily converted to PCB and back annotated.
Verification and Spice export for simulation allow for full project analysis. The DipTrace PCB layout module offers smart manual routing, shape-based autorouting, advanced verification, and 3D previewing.
Design rules can be defined by net classes, class-to-class rules, and detailed settings by object types for each class or layer. DipTrace features a design process with real-time DRC, which reports errors on the fly before actually making them. The board can be previewed in 3D and exported for mechanical CAD modeling. Design Rule Check DRC with in-depth detailing, net connectivity verification, and comparing to source schematic ensure maximum quality of the final design.
You can design the schematic in DipTrace, but if you wish to outsource the PCB layout the schematic will probably need to be exported to a PDF file, then manually redrawn in the new software package by the PCB layout engineer. So if you have any doubts which package is right for you, then I highly recommend that you download and test their free versions first. I think you will find that DipTrace is the only software that is intuitive enough to allow you to create your design immediately without spending hours reading the manual.
Most likely, unless you read the manuals, you will get very frustrated trying to use Eagle, OrCad, or Altium. If you need to work with other engineers on the same project then Altium Designer is probably the best choice. All of them offer free trial versions though so if you are unsure I suggest you download the free trials and compare them for yourself.
Protel SE was once wide spread, was taken over by Altium. How is Altium compared with the old Protel SE? More or less professional? I first heard of Predictable when my client acquired your services for a hardware report when they were looking at some next gen concepts. I appreciated that fresh perspective that you brought to the table and we found really good value in your report. They upped the ante over the past few years and now offer DesignSpark Mechanical. Feel free to email me at info null predictabledesigns.
Great article! Suggestion: display dates on the comments. That would be helpful. Why not start with the free day trial? Hi John, asking your layout engineer to new a learn a new software package would be very unusual and very inefficient.
Do you really want to pay him for the extra hours it will take for them to learn a new tool? Also they would need to buy new software, and will likely require you to pay for it.
We have to weigh that against the extra hours to manually redraw the layout in the new software. The engineer might be motivated to expand their skillset. Conversion: Direct conversion to their package might be possible. I have used OrCad, and Eagle. I have used Eagle for years and looking back it took me some time to learn. At my work the company has decided to use Altium and I have been hearing from coworkers that Altium is taking some time to get used to.
I was up and running with complete install and making schematics in the same day. I found that KiCad was very intuitive.
I recommend KiCad. These Diptrace fans made the switch to KiCad. Thank you for a very informative review. I have one question. At this price would you recommend Orcad over DipTrace? The only functionality these dummies ever have is daisy-chained connections for continuity testing.
I sometimes put a lot of stuff on a TV, usually with no or few connections. It would be more helpful in taking a little time to take on due diligence of the players ranked by seats in use, popularity if you will. Even the very expensive tools offer a trial period. Your favored tool is in the middle of the pack as far as instinctual use, and you get what you pay for as it has it quirks as any software does.
Your comments on libraries is somewhat misleading as the major distributors are offering vast libraries that output library files that you can integrate into your own at will.
I will say that such libraries whether a default offering from the tool or from part distributors, or 3rd party apps, need to be verified by the designer. In reality each designer should come to learn the basics of library creation, its impacts on reliability, manufacturability known as DFM, DFT.
Otherwise, how do you confirm to yourself, your customer, your employer that you have vetted a given footprint and accuracy of connectivity of a CAE symbol. Errors in library parts historically create coffee coasters, lost time, and lost business. Net list management, mitigating errors and collisions, gerber outputs have improved much in so many decades. If you put in enough years in this discipline you run into incorrect footprints, incomplete CAE symbols and even incorrect data sheets.
I had in one case three incorrect data sheets for the same part, different sources with the fourth being actually right. Document control and language translation issues from oversees manufacturers are not unheard of. It does not make your customers very happy no matter how legit that the error was beyond normal and expected diligence. We have gotten away from having parts in hand before tape out and we place a lot of trust in a number of engineering data sources. You have to add to your tasks the vetting of these sources.
The layout … Read more ». Thanks for the comment though! That is a great tool as well. Yes, KiCad is pretty good. The 5. I just discovered this website and liked this article, but there are no dates! Please consider adding dates to your articles. Great article. Are simulation software any good? Like Proteus? Being able to work out bugs before committing to board should be a plus. Thanks for this series of articles. I am retired now and I use DipTrace on a non-commercial basis, and I like it a lot.
EAGLE EDA used to be free, not sure how much is still free now that Autodesk owns it, but regardless, as the time I used it the user interface was way too dense for casual use.
Thank you Mark for the feedback and for sharing your experiences with Diptrace and PCB design in general. Much appreciated! Speed of design, as in pins per hour over the whole design process. Detailed control over layers, such as tenting vias instead of them being automatically open. I used Orcad for years, then Protel. Also, another one that was full featured but had the worst customer support on earth, with the developer himself an arrogant SOB.
I tried Eagle, 3 x and hate it every time. I recently tried Pads and, like Eagle hated it. Try that with DipTrace. DipTrace has some other issues that one discovers after a long time use. Thanks Bob for sharing your experience with everyone. The only downside I see is that looks like you always need an internet connection.
Thanks for the comment. Sorry brother but the three you listed are not even close to the top of the line.
No Typo. Thirty thousand dollars US. So you might want to broaden your PCB layout facts. Thanks for the comment Brad. Free, no limits on board size or layer count. Has a really nice push routing feature. Downsides are mostly graphical IMO; some refresh issues. I assist in the recommendation of KiCad: jumped recently into this due to several reasons.
And creating all the manufacturing files is so easy. For all the same reasons, I use KiCad for my designs.
I wrote it because I use DipTrace everyday and I happen to really like it.

Pros: Eagle CAD is easy for hobbyists just starting with printed circuit CAD designs and includes free options for limited tool versions. Cons: This software is not mainstream with corporate businesses that have internal PCB designers.
Also, using this tool for higher technology boards requires more manual calculations and routing than the higher-end CAD tools. This is open-source software. This free PCB design software can also check the circuit design flaws. Aside from the possibility to print your projects, you can use TinyCAD to publish your drawings by copying and pasting them into a Word document or saving them as a PNG bitmap image for the Internet. You can also use it as an interface for other PCB layout tools.

The tutorial touches on many of the areas of the software that you will need to become familiar with in your day-to-day design work. What better way to familiarize yourself with and get to know your powerful design 'partner'? To handle your valuable design data while affording unparalleled collaboration, Altium Designer can connect to and work with a Workspace. The Workspace not only provides rock-solid, secure storage of data but also enables re-release of data as distinctly separate revisions — essentially tracking design changes over time without overwriting any previously released data.
It also caters for the lifecycle of the data to be managed, allowing people that need to use the data to see at a glance what stage the data has reached in its 'life' and, therefore, what it can be safely used for.
The Workspace is used to manage all design data, including components, domain models, schematic sheets of circuitry, and design templates. Indeed, you can even create and manage your entire design projects directly within the Workspace. By furnishing a set of reusable design 'building blocks' within the Workspace, you can embark on fresh projects safe in the knowledge that each model, component, and higher-order design element has been ratified and approved for use, without having to reinvent the wheel as it were.
The Workspace becomes both the source and destination of design elements, with each new design utilizing elements released to and managed through the Workspace. Additionally, by designing only with elements from the Workspace, the integrity of those designs is inherently assured.
With an Altium Workspace, you'll benefit from a richer set of collaborative features, including Global Sharing. And because it is cloud-based, you get the latest version of the Workspace without having to worry about manual upgrades. Schematic capture is the process of creating a logical representation of an electronic circuit.
When you capture a schematic, you are connecting a collection of symbols components together in a unique way, creating your unique electronic product. When you perform your schematic capture electronically, you can create more than a high-quality printed representation of the design, perform related design tasks, such as a circuit simulation, and transfer the design to a PCB layout tool. Circuit simulation allows the designer to explore their ideas before committing to manufacture.
Concepts can be verified and the circuit can be tuned quickly and accurately. Circuit simulation also gives the designer the opportunity to perform measurements that may not be physically possible on the workbench. The Simulator is a true mixed-signal simulator, meaning that it can analyze circuits that include both analog and digital devices.
The Simulator uses an enhanced version of the event-driven XSpice. Inside every electronics product is a printed circuit board, or PCB. Today, the components have shrunken so much they are measured in fractions of a millimeter rather than centimeters, and track widths have shrunken from being 10 mil wide, well spaced lines, to thin, 2 or 3 mil hair-like lines that are tightly packed together. Rising signal speeds has also seen the PCB interconnects change from being simple copper conduits that carry electrical energy, to behaving as high-speed transmission lines, requiring design techniques to cater for this.
The mechanical requirements have also become more complex. Compact, unusually shaped modern electronic products require compact, unusually shaped printed circuit boards which are often implemented as rigid-flex structures - these boards can have curved edges and cutouts, requiring carefully positioned components.
Draftsman provides an advanced, yet flexible graphical editing environment for creating board design production documents. Based on a dedicated file format and set of drawing tools, the Draftsman drawing system provides an interactive approach to bringing together fabrication and assembly drawings with custom templates, annotations, dimensions, callouts, and notes.
Draftsman offers automated placement of assembly and fabrication drawings on demand, and includes a wide range of manual drawing tools that can be used to add important details and highlighting to its multi-page documents. The final phase of the board design cycle is to generate the output files needed to fabricate, assemble and test the printed circuit board.
To do this, you need to generate a variety of output files in a variety of formats. As the designer, you have the choice of individually configuring and generating the outputs via the schematic and PCB editor, or alternatively, you can add all of the required outputs into an OutputJob and then generate them as part of the project release process.

Can I add a FET in parallel to this boost circuit. Thread starter DarrenB Start date Jul 7, DarrenB New Member. I use these AliExpress boost converters to charge batteries but I would like to make it function closer to its rated specifications. I have tried replacing the fan with one that has a higher static pressure rating and it helped considerably but I was thinking I could take it further by adding a larger heatsink and another FET in parallel.
Is it possible to add an identical FET in parallel to this pre made boost converter? I know that the total heat will equal roughly the same but I am more concerned the thermal path being larger and the heat being shared across two packages. I am a complete beginner when it comes to electronics so please forgive me if this is a stupid question. Sort by date Sort by votes. Lightium Member. So yes, you will need low resistance resistors on each source pin.
Upvote 0 Downvote. It would probably make it even worse A common problem with cheap devices using large power FETS is the circuit not having enough gate drive current, so the power device does not switch as fast as it could - and it's when it is part on that the power dissipation is very high. The existing device has a typical gate capacitance of 7. Click to expand Remember the output limit is 10A; you can only [theoretically] achieve W at over 80V output.
What input and output voltages are you using? Also of concern is gate drive R typically used to suppress parasitic L transients, eg.
Make sure that R has sufficient power handling capability. The dissipation due to "on" resistance at 30A eg. All the heat is due to dissipation while it is changing between fully off and fully on.
Lightium said:. Last edited: Jul 11, Bi-polar transistors do need resistors to balance their current, but MOSFETs have a positive temperature coefficient for their on-resistance so will inherently tend to share the load current when used as switches, no source resistor needed. And typically since multiple MOSFETS typically in the same thermal environment they all experience similar heat rise, mitigating some of the beneficial effect of rising Rdson with T.
Not to lose full insight this is all non linear and starting at different points on the Rdson vs T curve for each device I would still want to swamp out that variation with ballasting unless I match at device test. Regards, Dana. Ballasting in this context is to insure MOSFETs that are paralleled, when on, one of them do not hog most of the current thereby overloading it.
So one adds R in series to mitigate device to device Rdson variation and Vth varia- tion where one turns on before the others.

I have tried reading through things like this before but each and every hurdle will spur another question. I think I need to understand the basics of electronics. Electronics is a bit like a puzzle for me where the more you learn the easier it becomes. It can also be a bit like having a missing critical part to a math equation.
Understanding what the values on data sheets are and how they interact with one another would probably also help. How did you learn electronic engineering? Self taught or an education program?
