  • Abstract
    An area efficient switched capacitor charge pump based 2ntimes voltage converter constructed by cascading n units of identical cells with cross-coupled charge pump is proposed and is implemented with a boosting dynamic circuit to provide level shifting. The proposed charge pump can be implemented using standard high-voltage CMOS process. Simulation result of a 4times charge pump based on 0.35 mum CMOS technology is presented to demonstrate the effectiveness of the proposed circuit.
