摘要： The present invention discloses a charge pump system with low noise and high output current and voltage, comprising: a four phase clock generator used to generate a first signals group; a serial of delay circuits coupled to said four phase clock generator, wherein each of said delay circuits is coupled to a previous delay circuit relative to each of said delay circuits for delaying a signals group received from said previous delay circuit; a first charge pump circuit coupled to the four phase clock generator and the delay circuits; and an output terminal coupled to the first charge pump circuit; wherein high level of said first signal overlaps two sections of high level of said third signal to generate a first overlapping time and a second overlapping time, and said first overlapping time is not equal to said second overlapping time.
