ABSTRACT:
A charge pump includes a level shifter and a charge exchange control switching circuit. The level shifter can enhance the levels of a first and second clock signals, and output a first and a second control signal corresponding to the enhanced signals. Based on the first and second control signals, the charge exchange control switching circuit amplifies an input voltage and generates a corresponding amplified output voltage.
