N2 - This paper presents a boost converter with the maximum power point tracking (MPPT) technique for thermoelectric energy harvesting (EH) applications. The technique realizes variation tolerance by adjusting the switching frequency fSW of the converter. A finely controlled zero-current switching (ZCS) scheme together with the accurate MPPT technique enhances the overall efficiency (η) of the converter because of an optimal turn-on time generated by a one-shot pulse generator that is proposed. Moreover, the ZCS technique can deal with low and high temperature differences applied to the thermoelectric generator. Experimentally, the converter implemented in a 0.35 um BCDMOS process had a peak of 72% at the input voltage VIN of 500mV while supplying a 5.62V output.
