    Abstract

    A high efficiency charge pump which is suitable for energy harvesting application is proposed. By introducing a pre-charge circuit and a new charge sharing clock scheme, the dynamic power loss caused by parasitic capacitance is reduced by nearly a half. Under an ultralow supply voltage of 0.45V, simulation results show that the efficiency is improved by more than 10%.
