The present invention discloses a regulator system (112) for regulating the output current and voltage (Vout) of a charge pump circuit (104). It is observed that the output current and voltage (Vout) of a charge pump circuit (104) can be regulated by varying the amplitude and frequency of a set of clock...http://www.google.com/patents/US6188590?utm_source=gb-gplus-sharePatent US6188590 - Regulator system for charge pump circuits
