Fully Digital Adaptive PMU-MCU System For Hybrid (Battery-Harvester) IoT Devices


A new technical paper titled "An Ultra-Low-Leakage Microcontroller with Configurable Power Management for Energy Harvesting IoT Devices" was published by researchers at Eindhoven University of Technology and Innatera Nanosystems. Abstract "This paper presents a power management unit (PMU) architecture designed for energy-harvesting IoT devices, integrating a dual-capacitor system, an ultra-... » read more

Margin Sensors In The Wild


Back in March, I wrote up an article here that looked at how a proxy circuit could be used to measure variations in circuit performance as conditions changed in the operating environment. There were a couple of recent presentations on margin sensors at two of the big EDA vendors' customer engineering forums that we’ll look at as well as another product with an upcoming presentation at DAC. Ma... » read more
