Exemplary embodiments of a power supply can be provided. The exemplary power supply can include a voltage source which supplies a supply voltage; and a charge pump circuit supplied by the voltage source and configured to generate an output voltage at an output. The charge pump can include alternating first and second clock states. In the first clock state, a first charge pump capacitor can be disposed between the supply voltage and ground and can be charged to the supply voltage by the voltage source, and a second charge pump capacitor can be coupled in series between the voltage source and the output. In the second clock state, the first charge pump capacitor and the second charge pump capacitor can be connected in series such that the charged connection of the first charge pump capacitor the first clock state can be grounded and the second charge pump capacitor can be charged by the voltage source.
