Abstract: A charge pump provides an output voltage with reduced voltage ripple. The charge pump includes a first capacitor, a second capacitor, and a control circuit. The control circuit charges the first capacitor to one of a first voltage and a second voltage and the second capacitor to the other one of the first and second voltages using differential clock signals and an input voltage during each clock phase and outputs the higher one of the first and second voltages as an output voltage.
