摘要：
Charge pumps and methods for regulating charge pumps. The charge pump includes a voltage booster circuit and a voltage regulator circuit. The voltage booster circuit includes first and second input terminals that respectively receive a regulation voltage and an input voltage. The voltage booster circuit generates an output voltage having a polarity that is different from the input voltage. The output voltage is adjusted by the regulation voltage and provided to an output terminal. The voltage regulator circuit is coupled between the first input terminal and the output terminal of the voltage booster circuit. The voltage regulator circuit shifts the output voltage to a level shifted voltage and generates the regulation voltage responsive to the level shifted voltage.
