Summary: This paper presents a self-startup and ultra-low-voltage boost DC-DC converter for thermoelectric energy harvesting. The converter achieves a minimum self-startup voltage using a two-stage auxiliary boost startup circuit, and is capable of sustaining operation at a 15 mV input. The proposed maximum power point tracking (MPPT) scheme, combined with coarse and fine frequency tuning, improves tracking accuracy and reduces output ripples. By combining the zero current switching (ZCS) scheme with MPPT, the converter achieves a peak end-to-end efficiency of 71% and provides a regulated 1.25V output with a maximum power of 540 mu W.
