Abstract
A variable-frequency electric charge pump unit, a chip, and a communication terminal. The electric charge pump unit comprises a variable-frequency signal generator, an electric charge pump circuit, and a voltage detector connected in series. The variable-frequency signal generator outputs a clock signal for the electric charge pump circuit. The electric charge pump circuit generates an output voltage on the basis of the clock signal. The output voltage drives a load on the one hand and is connected to the voltage detector on the other hand. An output end of the voltage detector is connected to the variable-frequency signal generator. The working frequency of the variable-frequency signal generator can be adjusted dynamically on the basis of a requirement that a radiofrequency system work state has on the driving output of the electric charge pump unit.
