Abstract

Integrated circuits for wireless sensor nodes (WSNs) targeting the Internet-of-Things (IoT) paradigm require ul- tralow-power consumption for en ergy-harvesting operation and low die ar ea for low-cost nodes. As the IoT calls for the deploy- ment of trillions of WSNs, minimizing the carbon footprint for WSN chip manufacturing further emerges as a third target in a design-for-the-environment (DfE) pe rspective. The SleepWalker microcontroller is a 65-nm ultralow-voltage SoC based on the MSP430 ar
