Patent ID: 7888989

Claim:
A charge pump regulator for regulating a voltage on an output terminal, comprising: an input terminal for connecting with a power supply; a charge pump connected between the input terminal and the output terminal, for being operative to establish a charge path and a discharge path alternately; a feedback loop for producing an output-dependent feedback signal, charge pump having at least a current control element on the charge path or the discharge path for controlling a current flowing therethrough according to a drive signal derived from the output-dependent feedback signal; and a connector for connecting the drive signal to the current control element and disconnecting the drive signal from the current control element, the connector including: a transmission gate for connecting the drive signal to the current control element in a first phase; and a switch for connecting a voltage to turn off the current control element in a second phase, the voltage to turn off the current control element being the regulated voltage on the output terminal.
