A new low voltage charge pump is developed to help start up a step-up converter in energy harvesting applications. The proposed charge pump is the first to utilize both backward control scheme and two branches of charge transfer switches (CTSs) to direct charge flow. The backward control scheme uses the internal boosted voltage to dynamically control the CTSs' gate, and the two branches utilize both NMOS and PMOS to implement their switching structure. The combination of backward control scheme… CONTINUE READING
