Abstract:
A circuit includes a charge pump and a feedback circuit. The charge pump coupled to a switch provides a control signal to the switch. The feedback circuit coupled to the charge pump receives the control signal and adjusts an operating frequency of the charge pump based upon the control voltage. The control voltage is adjusted to a predetermined target voltage by adjusting the operating frequency through the feedback circuit.
