Abstract
A new approach for improving the power efficiency of the conventional four-phase charge pump is presented. Based on the multi-step capacitor charging and the charge sharing concept, the charge pump design is able to reduce the overall power consumption by 35% compared to the conventional four-phase charge pump and by 15% compared to a charge sharing charge pump, for an output current of 200μA with 12V output voltage.
