Abstract: Techniques of providing a low output voltage, high current capability charge pump are given. The charge pump has multiple capacitors along with switching circuitry. In an initialization phase, the first plate of each of the capacitors is connected to receive a regulator voltage and the second plate of each capacitor is connected to ground. In a transfer phase, the capacitors are connected in series, where, for each capacitor after the first, the second plate is connected to the first plate of the preceding capacitor in the series. The output voltage of the pump is from the first plate of the last capacitor in the series. Regulation circuitry generates the regulator voltage from a reference voltage to have a value responsive to the output voltage level of the pump.
