Abstract
Disclosed in the present invention are a charge pump circuit, a chip, and a communication terminal. The charge pump circuit comprises a phase clock generation module, an acceleration response control module, and a plurality of sub charge pump modules. By generating a plurality of clock signals with a fixed phase difference by means of the phase clock generation module, correspondingly controlling the plurality of sub charge pump modules to generate output voltages, and by means of the acceleration response control module, measuring the output voltage of each sub charge pump module, and separately outputting a logic signal to the phase clock generation module and each sub charge pump module, the frequency of the clock signals outputted by the phase clock generation module is changed, and the charge and discharge time of a capacitor in each sub charge pump module is reduced.
