A charge pump is disclosed wherein a transistor of the charge pump is modified to regulate a supply voltage to substantially reduce noise from the supply voltage when charging the capacitor of the charge pump and subsequently reduce noise at the voltage output. The charge pump may have a regulating transistor for charging or for pumping or for both. The regulating transistor requires a regulated bulk voltage and a modulated gate voltage to enable regulation of the supply voltage. The regulated bulk voltage being supplied by a small regulator.
