Abstract :
In this paper, a fully integrated low voltage charge pump for thermoelectric energy harvesters is presented. The proposed dual-mode architecture achieves both the low startup voltage in a startup mode and high conversion efficiency in a normal operation mode without off-chip inductors and capacitors. In the measurement, the proposed circuit successfully converts 120-mV input to 770-mV output with 38.8% conversion efficiency.
