This paper presents a theoretical study on clock control strategy of four-phase Dickson charge pump for improving the power efficiency. Optimized clock control signals attains better power efficiency when compare the conventional designs. Simulation results based on the 0.25 mum CMOS technology are presented to validate the analysis.
