Abstract :
An on-chip ripple reduction system for a regulated two-phase voltage doubler charge pump circuit is presented. Simulated results show that ripple reduction ratios up to 53% can be achieved when the designed ripple reduction solution is applied over a 5 V regulated charge pump with flying and load capacitors Cf = CL = 1 muF, switching frequency fs = 100 kHz, and load RL = 10 kOmega.
