Abstract

A thermo-electric energy harvesting based regulator system with output power maximization for high conversion ratio and very low input voltages, suitable for low power biomedical applications is presented. An optimal control topology for an inductor based regulator is implemented. Zero Current Switching is achieved by Pulse Width Modulation. Feedback mode control regulates output voltage to 1V with maximal load support. The system delivers peak power of 1.5mW and 19uW at 100mV and 11 mV input, respectively. The post-layout simulations done in UMC 180nm CMOS, show peak efficiency of 68% at 11mV input to boost converter.
