Abstract
A charge pump generator system and method is provided in which one or more charge pumps are operated at multiple charging rates depending upon the level reached by a voltage supply. The system includes a limiter which provides a control signal based upon the level of the voltage supply. The control signal selects the frequency of a multiple frequency oscillator coupled thereto. The selected frequency determines the charge transfer rate of a charge pump used to maintain the voltage supply.
