We know that energy is all around us, but how exactly do we harness it? To start things off this week, we take a closer look at an interesting new energy harvesting technology developed at MIT called a “thermal resonator.” By utilizing the gradual ambient temperature changes that occur over the course of a day, this technology can literally pull electricity out of the … Read More → "It’s Getting Hot in Here"
For the five decades of Moore’s Law, the main thrust of semiconductor technology advancement has been about shrinking geometries, lowering voltages, and lowering power consumption. Silicon CMOS has dominated that domain, of course, and most of the world’s semiconductor production is now CMOS for digital circuits.
Quietly, however, significant progress has been made on … Read More → "Wide Bandgap Wakes Up"
From source to sink to the current in-between, this week’s Fish Fry is all about power delivery and how we can solve our power delivery network problems. My guest is Brad Griffin (Cadence Design Systems) and we’re talking about how we can catch the PDN issues earlier in our design cycles and how “shifting left” can make all the difference in your next PCB design. Keeping with … Read More → "Climbing the PowerTree™"
Let’s start by getting one thing straight: Minima Processor is not a processor company. It’s a processor-related IP company, and, most specifically (at least for now), it’s a DVFS (dynamic voltage and frequency scaling) IP company.
If you’re not familiar with DVFS, it’s a way of changing power … Read More → "Dynamic Voltage and Frequency Schooling"
A couple of years ago, we covered a company that was working to make power supplies more efficient. Today we update that story. But… if you take the company name today and try to find the old article, you’ll have a hard time: they’ve changed their name from Semitrex to Helix.
With that detail out … Read More → "A Wooden Stake?"
There’s an elephant in the room. You know it and I know it too. Whether we start with the trunk or the tail, the truth is clear. Our power grids are overtaxed, transformer technology has hit its limit, and “vampire power” (stand-by power wasted) is becoming a bigger problem than ever before. What can we do about our aging, overtaxed, and under-loved power grid? In this week’s … Read More → "Vampire Power and the Curious Case of the MuxCapacitor"
