Abstract: A charge pump circuit includes a plurality of serially coupled stages and a plurality of clock drivers. A voltage output of a first of the stages is connected to a voltage input of a second of the stages. A voltage output of the second of the stages is boosted relative to a voltage input of the second of the stages. Each of the stages includes complementary charge pumps. Each of the charge pumps includes a pumping capacitor that stores charge in the stage. Each of the clock drivers drives a clock signal to the pumping capacitor of at least one of the stages. A voltage of the clock signal provided to the second of the stages is derived from the voltage input of the second of the stages.
