A nano quiescent current power management for autonomous Wireless sensor network

Abstract

A Nano quiescent current Power Management for Autonomous Wireless Sensor Network dedicated to indoor and outdoor Photovoltaic (PV) Energy Harvesting is presented. The standby current consumption is 130nA @ 2.4V. The battery can be charged with less than 5% of the harvested energy from low light (70 lux) to high light (1 sun). The IP starts charging at light level as low as 10 lux providing ≃ 1μW. The voltage range is 2.4V - 3.2V. The system load can be powered up to 400mA. This power management is manufactured using the CMOS 90nm technology in a 0.4mm2 die area.
