Hidden Analog Technology at the 2014 ISSCC
Doug Grant 1/28/2014 9 comments
The International Solid State Circuits Conference kicks off February 9. While the mass media will focus on the biggest memory, faster processor, and smallest geometries reported, I prefer to look at the analog stuff.
Bring Back the Analog Computer
Derek Koonce 1/27/2014 11 comments
Analog computers were popular and useful a long time ago. With the advent of digital computing technology, it may seem like analog computers are no longer useful to the designer. You may be surprised at the many areas that analog computing can provide an advantage over the newer and more powerful digital technology.
ADC Noise: How the Clock Input Can Help
Jonathan Harris 1/24/2014 4 comments
One of the most critical areas on an ADC that can affect performance is clock noise. Good layout and routing techniques coupled with an optional filter can do wonders in improving key specs.

We continue looking at the ways to measure and evaluate the amount of energy stored in rechargeable lead-acid cells.
Baby, You Can Drive My BLDC

Controlling power to a 3-phase brushless DC motor requires care and finesse. Here's a design kit (eval board) that makes it easy.
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.
