Abstract : This paper presents architecture of an ASIC based energy harvesting system from four sources solar, thermal, vibration and RF. A capacitor based start-up circuit is used for batteryless self-start and a supercapacitor based storage mechanism is employed for storing the harvested energy. The system includes Maximum Power Point Tracking logic based on Perturb and Observe algorithm for tracking and extracting the maximum power from solar PV source. Rectifiers and DC-DC Converters are used for extracting energy from AC sources (RF and Piezo) and thermal respectively. The system was simulated in Cadence virtuoso. Efficiencies achieved with different sources are 79.06% for Solar PV, 72.618% for Thermal, 63.84% for Piezo and 56.793% for RF. © 2015 IEEE.
