Abstract
The charge pump system includes a clock generator, a boosting unit determination device, a charge pump circuit, and a voltage regulator. The clock generator is used for generating a clock group. The boosting unit determination device is used for generating a number control signal. The charge pump circuit is used for receiving an operating voltage, the number control signal and the clock group, and generating an output voltage. The charge pump circuit includes plural boosting units. A first portion of the plural boosting units are controlled by the clock group according to the number control signal. The operating voltage is converted into an output voltage by the first portion of the plural boosting units. The voltage regulator is used for receiving the output voltage and converting the output voltage into a specified regulated voltage.
