Abstract :
We present a processor, the Digital Power Manager (DPM), providing power management and node/data/processing flow control for a 130nm battery-less power harvesting body sensor node. The DPM adjusts node power consumption, responding to available energy to support operation exclusively from harvested power. The DPM consumes 2.5pJ/instruction and 0.63pJ/cycle for NOPs.
