A charge pump comprising a first branch PMOS FET having a source connected to a voltage source and a drain connected to an output node, a second branch NMOS FET having a drain connected to the output node and a source connected to a ground node, first apparatus for selectively switching a gate of the PMOS FET between its source and a first bias voltage source, and second apparatus for selectively switching a gate of the NMOS FET between its source and a second bias voltage source, the bias voltages being of magnitudes such that the first branch PMOS FET and second branch NMOS FET will source and sink the same magnitude of current when the FETs are fully conducting.
