ABSTRACT:
An improved charge pump circuit includes a charge pump capacitor having first and second terminals for charging in first and second polarities; a current source device for supplying current selectively to the charge pump capacitor through the first and second terminals; a clamping device for defining first and second clamping voltages for the first and second terminals, respectively; a switching device for selectively connecting the current source device to one of the terminals and connecting the clamping device to the other of the terminals; and a clamp control device, responsive to the differential mode voltage across the charge pump capacitor, for setting the clamping voltages to obtain a difference between the clamping voltages equal to said differential mode voltage and pumping equal charge into the charge pump capacitor in either polarity.
