Abstract
A charge pump includes a first current source, a second current source, and a current mirror. The first current source is included to set a common mode output voltage of a charge pump core based on a desired common mode input of the charge pump core. The second current source is included to receive the common mode output voltage from the charge pump core. A first input of the current mirror receives a signal from the first current source, and a second input of the current mirror receives a signal from the second current source.
