  • Patent number: 8450991
    Abstract: This disclosure describes an invention that is a basic charge recycling gate 70 that includes a precharge node 75, a output charging network 78, an output pre-charge and null propagate network 77, an evaluation network 76, a first time varying power supply TVS0, a second time varying power supply TVS2, and a keeper circuit 79. Additionally, this disclosure describes an invention that is a time varying power supply 130 that includes a resonator circuit 131, an amplitude and power check circuit 135, one or more overshoot and an undershoot voltage clamps 1105 and 112, exciter circuits 137 and 136, and current monitor circuits 138 and 139. In addition, the invention includes frequency self tuning with the amplitude and power check circuit 135, capacitor banks 132 and 134, and the inductor tap select controller 133. Amplitude self tuning is provided by the amplitude sample and compare circuit 144. Further, a phase shift control circuitry 150 is also provided.
