Claim 16:
17. 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 second input of the comparator;
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 second 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
a counter interposed between the second output of the clock generator and the input of the second open-loop charge pump.
