MIPI Creates the I3C Sensor Interface
Steve Taranovich 12/31/2014 13 comments
I recently spoke to Ken Foust from Intel regarding his being the chair of the MIPI Sensor Working Group and the important standards work they are doing there. I also had a conversation with Peter Lefkin, the Managing Director of the MIPI Alliance about I3C.
The Big Lie About LEDs
Scott Elder 12/22/2014 51 comments
The world has been told that LEDs are the future, in part because they are economically the right form of long-term lighting and there are environmental benefits as a great aside. Well, maybe the environmental argument is true, but the economical one is not.
What’s Driving Interest for Supercapacitors?

Chances are you’ve heard mention of supercapacitors if you haven’t yet implemented them in a system design. That’s because when components experience a 30% compound annual growth rate, it is usually driven by game-changing advantages.
An AC Current Generator, Part 2

When testing, a 10 amp AC current is fed into the module being tested (DUT) and the current is measured across a 25 mΩ shunt internal to the DUT.
The STEM of All Evil

One thing very gratifying over the last few years is the rise of the MAKE meme: Experimenters and hobbyists are back in fashion with our youth.
EDA Tools Should Be Free
Scott Elder 12/4/2014 5 comments
The evolution of technology is being hindered by the lack of high-end tool access. Most innovation originates from small organizations with little or no money to pursue their visions.
An AC Current Generator, Part 1

I wrote an article on this topic in 2000 that was published on Circuit Cellar Online. I believe that the basic information that I wrote about is still relevant and so I am rewriting the article as a blog.
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.
