Abstract
A charge pump circuit includes a boost capacitor driven by a first clock signal and a bootstrap capacitor driven by a second clock signal. The first and second clock signals have different duty cycles, with the duty cycle of the second clock signal being smaller than the duty cycle of the first clock signal. An input transistor is coupled between an input node and a boost node coupled to the boost capacitor. The control terminal of the input transistor is coupled to the bootstrap capacitor. A bootstrap transistor coupled between the boost node and the control terminal of the input transistor is driven by a logical inverse of the first clock signal.
