A method and apparatus for providing a clock signal to a charge pump is disclosed. In a particular embodiment, the method includes providing a first clock signal to a first charge pump unit of a charge pump. The method further includes providing a second clock signal to a second charge pump unit of the charge pump. A low-to-high transition of the first clock signal occurs substantially concurrently with a high-to-low transition of the second clock signal. Only one clock signal may be at a logic high voltage level at any given time.
