【Abstract】 A regulated charge pump circuit is realized in the HEJIAN 0.18um triple-well CMOS technology. The power efficiency is increased by changing the output stage architecture of the four phase charge pump. A low-ripple output voltage is obtained based on improving the conventional clock blocking scheme.更多还原
