Abstract
A charge pump circuit includes a first charge pump unit and a second charge pump unit. The first charge pump unit pumps an input voltage to output a first pumped voltage according to a first clock signal, a second clock signal and a third clock signal. The second charge pump unit pumps the first pumped voltage to output a second pumped voltage according to the first clock signal, a fourth clock signal and the third clock signal. The first clock signal and the third clock signal are non-overlapping clock signals. A falling edge of the second clock signal leads a rising edge of the first clock signal. A falling edge of the fourth clock signal leads a rising edge of the third clock signal.
