SEMICONDUCTOR DEVICE WITH CHARGE PUMP BOOSTER CIRCUIT

摘要

PROBLEM TO BE SOLVED: To output a desired boosted voltage not limited by an integer times of an input voltage in a charge pump booster circuit, and to output a boosted voltage stabilized against variation in load. SOLUTION: Boosted voltage is controlled by controlling the gate voltage of a pumping transistor depending on the feedback voltage of the boosted voltage. COPYRIGHT: (C)2007,JPO&INPIT
