Claim 0:
1. A regulated charge pump comprising:
a comparator having a first input and a second input for receiving a reference voltage;
a clock generator having an input coupled to an output of the comparator;
a first open-loop charge pump in a first feedback path having an input coupled to a first output of the clock generator, and an output coupled to the first input of the comparator; and
a second open-loop charge pump in a second feedback path having an input coupled to a second output of the clock generator, and an output coupled to the first input of the comparator,
wherein the output of the first open-loop charge pump and the output of the second open-loop charge pump comprises an output of the regulated charge pump, and wherein the first output of the clock generator is configured for providing a first clock signal having a first frequency, and wherein the second output of the clock generator is configured for providing a second clock signal having a second frequency different from the first frequency.
