Abstract :
A charge sharing clock scheme is proposed to feed a 5-stage double charge pump circuit. By reusing the charges in charging or discharging the parasitic capacitance during the pumping process, dynamic power loss is able to be reduced by nearly a half. Under 1V supply, simulation results show a maximum 10% efficiency increase, and the ripple noise is also reduced by a half comparing to the conventional charge pumps.
