Abstract
A charge pump circuit includes a pump unit and an output transistor for outputting a pumped voltage generated by the pump unit. The pump unit includes a first capacitor, a second capacitor, a first transistor, a second transistor, and an auxiliary control unit. The first capacitor receives a first clock signal, and the second capacitor receives a second clock signal having a swing greater than that of the first clock signal. The first transistor has a first terminal coupled to an input terminal, a second terminal coupled to the first capacitor, and a control terminal coupled to the second capacitor. The second transistor has a first terminal coupled to the second capacitor, a second terminal coupled to the second terminal of the first transistor, and a control terminal coupled to the auxiliary control unit, which turns on the second transistor when the first clock signal is high.
