(English Abstract)
In this paper a low-power MPPT(Maximum Power Point Tracking) interface is designed for low-voltage thermoelectric energy harvesting sources. The proposed circuit consists of an MPPT controller and a bias generator. The MPPT controller consists of an MPG(MPPT Pulse Generator) circuit to generate a pulse signal for MPP voltage generation and a sample/hold circuit to sample the open-circuit voltage of a thermoelectric input device. The bias generator is designed by employing a beta multiplier structure and a start-up circuit consisting of three MOSFET switches. The proposed circuit is designed with 0.35§­ CMOS process, and the chip area of the designed circuit is 817§­ ¡¿ 705§­. The simulation results show that the designed circuit operates properly at an input voltage of less than 200mV, consumes less than 190nA of current, and achieves a maximum power conversion efficiency of 95.0%.
