    Abstract

    A 4-phase cross-coupled charge pump with charge sharing clock scheme is proposed in this paper. Four phase clock is utilized to prevent the reverse leakage current. A charge sharing clock control circuit is constructed, and the consumption in charging or discharging the bottom plate parasitic capacitance of the boost capacitors is reduced by half. The proposed charge pump is overstress free and compatible for standard CMOS process. Simulation results show a maximum 10% efficiency increase more than that of conventional charge pump without charge sharing.
