These days, it’s all about keeping power down by all means possible. Power domains are a thing. Clock gating and power gating are a thing. Even applications can change the power state of the system.
All good, but let’s explore that last one a bit. In order for software to change the power, it has to go through the operating system. Which might seem kinda … Read More → "Sonics Does DVFS"
“The real secret of success is enthusiasm.” – Walter Chrysler
Last week I interviewed a real, live, professional race car engineer for the famous Andretti racing team, whose workshop and garages are based just outside the equally famous racetrack at Indianapolis. And what’s the first thing I learned?

Most of us think about capacitors the way a chef thinks about salt – knowing that it’s never the star of the show, having a keen awareness that you need just the right amount, being vaguely conscious of the fact that there are multiple, subtly different types… When we’re debugging our board, there are often times when something mysteriously isn’t working right. When all … Read More → "Aggressive with Passives"
Batteries have historically been perceived as something of a staid technology – at least in a lot of minds. I remember back when we were diving into 3-V standards at JEDEC many years ago, and we invited battery folks to help advise us. I came away with the distinct sense that battery chemistry was pretty much what it was and would always be. Yeah, I saw you stifling that yawn… … Read More → "Battery Roundup"
As an electronics editor, I am constantly being briefed on new technologies. Often, the presenter struggles to establish a framework for the innovation being described, trying to make a case for the big-picture importance of what they’re doing. Seldom am I left with a feeling that I am learning about an engineering development that could truly change the world.
This, however, was … Read More → "Sunshine Changing the World"
In this week’s episode of Fish Fry, we’re talking about embedded power, COTS, the next generation of rail systems, intelligent cooling systems, and whether I need a witch doctor to cool my next chassis-based design. Justin Moll (Pixus Technologies) and I jump head first into the world of chassis cooling and electronics packaging, and Qianqian Shao (Artesyn Embedded Technologies) and I ride the rails to the to … Read More → "The Science and Art of Cooling and COTs"
