A charge pump cell with an input and output nodes includes a first, second, and third equalization units, and a first, second, and third capacitors. The input node is coupled to the inputs of the first, second and third equalization units, and the output node is coupled to the second equalization unit. One end of the second capacitor is coupled to the control end of the first equalization unit for enabling or disabling the first equalization unit, and also coupled to the output of the third equalization unit. One end of the third capacitor is coupled to the output of the second equalization unit. One end of the first capacitor is coupled to the control ends of the second and third equalization units, and also coupled to the output of the first equalization unit.
