Abstract
A charge pump circuit is provided. The charge pump circuit includes a plurality of voltage-boosting stages connected in series with each other and having a supply terminal, a control terminal, and an output terminal respectively, and a plurality of voltage multipliers, each multiplier having an input terminal, a first output terminal for outputting a first clock signal, and a second output terminal for outputting a second clock signal respectively, wherein the input terminal of a first voltage multiplier is coupled to a clock signal, a magnitude of the first clock signal is a multiple of a magnitude of the second clock signal, each of the voltage multipliers is coupled the respective second output terminal thereof to the input terminal of a downstream voltage multiplier, and the first output terminal of the voltage multiplier is coupled to the control terminal of a respective one of the voltage-boosting stages.
