Abstract :
We present initial experimental results of our low-power RF energy harvester that includes a charge pump, voltage regulator and a bandgap voltage reference in CMOS 130nm technology. The DC regulator designed for RF IC energy harvesting applications and optimized for powering implantable electronics. The internal circuit sections work with the local power supply voltage levels in the 1.5-1.9V range (worst case), and the 6.28μW bandgap generates 459mV DC reference voltage. The complete regulator consumes typically 23.5μW for its own operation while delivering regulated VPWR = 0.97V DC voltage.
