Few analog IC design projects are more difficult than an on-chip voltage reference. If you think you know how to do this in bipolar technology, try getting it to work in CMOS. (As a test, check out how many of those highly-touted A/D converters we're now seeing have an on-chip reference.) Worse, try implementing a bandgap reference in 90nm CMOS. Building on the legacy of Bob Widlar, Clyde Washburn, a consultant and adjunct professor at the Rochester Institute of Technology shows us a new, licens

Articles  
4/6/2005   1 comment
Since the introduction of low dropout linear regulators in the early 1990's, the market for this subset of standard linear regulators has expanded and the requirements have become more finely tuned. Therefore, designers can no longer solve all application problems with a single device as they now have an entire portfolio of products to choose from for any given application. In an expanded version of an article which appeared in April's Planet Analog magazine, a Micrel engineer offers some insigh

There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
