  • High efficiency regulated charge pump
    Patent number: 8593213
    Abstract: Described herein are systems and methods for creating high efficiency regulated charge pumps. In an exemplary embodiment, a Dickson charge pump is combined with a low voltage amplifier to create an effective class G amplifier with high voltage outputs that achieves very high power efficiency. The charge pump capacitors are alternately driven by either the charge pump circuit or a low voltage amplifier which uses negative feedback from one or more high voltage outputs to give closed loop regulation.
    Type: Grant
