Abstract

This paper presents a cold-starting energy harvester in 65nm CMOS with source degradation tracking and automatic MPPT. A power-efficient architecture is proposed to keep the internal circuitry operating at 0.4V while regulating the output voltage at 1V using switched-capacitor DC-DC converters and a hysteresis controller. Peak efficiency of 86% is achieved at 0.39V input voltage and 1.34μW of output power with 220nW of internal average power consumption. Integrated operation with lactate biofuel cells is demonstrated.
