A single pump stage of a multi-stage charge pump couples a first low-voltage NMOS transistor in series with a first low-voltage PMOS transistor between charge transfer capacitors. A second low-voltage NMOS transistor is coupled between the gate and the source of the first NMOS transistor. A second low-voltage PMOS transistor is coupled between the gate and the source of the first PMOS transistor. Respective boost voltages are applied to gates of the first NMOS transistor and the second PMOS transistor to minimize threshold voltage losses. A stabilizing capacitor is connected between the first NMOS transistor and the second PMOS transistor.
