摘要

An energy-harvesting wireless sensor node (WSN) integrates a 14-nm, 0.79-mm2, 32-b Intel Architecture corebased near-threshold voltage (NTV) microcontroller (MCU) that provides 17-μW/MHz always-ON, always-sensing (AOAS) capability. The MCU implements four independent voltage-frequency islands, managed by an integrated power management unit and features a subthreshold voltage capable on-die oscilla...
