Full-Power WiFi at Half the Power

In IoTland, communication is king. It puts the Internet in the IoT. But how to communicate? LTE? BlueTooth? WiFi? It partly depends on the application and the location, but it also depends on how far you are from a wall plug.

Because many IoT devices are small, portable, and – this is key – battery-powered, they will forever be infinitely far away from the wall plug. While WiFi has … Read More → "Full-Power WiFi at Half the Power"

It’s Getting Hot in Here

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"

Wide Bandgap Wakes Up

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"

Climbing the PowerTree™

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™"
