Abstract: The present invention relates to a charge pump capable of enhancing power efficiency and output voltage, which comprises a pump capacitor, a switching module, a first switch, a first buffer, a first switch, and an output capacitor. The switching module is coupled to a first terminal of the pump capacitor. The first switch is coupled between a second terminal of the pump capacitor and a supply voltage. The first buffer receives a first input signal and produces a control signal for controlling the first switch to turn on or cut off. The level of the first input signal ranges between a first voltage and a second voltage, wherein the first and the second voltages are related to the gate voltage of the first switch. The gate voltage of the first switch is a multiple, which is greater than one, of the supply voltage. Thereby, the impedance of the switch is reduced, and hence the power efficiency of the charge pump, the output voltage level, and the area efficiency of integrated circuits are improved.
