This paper analyzes the output power of the thermoelectric generator (TEG) and continuously scalable-conversion-ratio SC converter for achieving low-power maximum power point tracking (MPPT) with switched-capacitor (SC) converter. In state-of-the-art SC energy harvesting interfaces, they transfer harvested power inefficiently due to fixed conversion ratios. Therefore, the proposed MPPT method harvest power based on the conventional open circuit voltage method, without additional open circuit voltage sampling period. The proposed energy harvesting converter is designed in a 180 nm CMOS process and is measured to prove that the power can be transferred properly with the analyzed power conversion modes.
