Abstract
This disclosure describes an invention that is a basic charge recycling gatethat includes a precharge node, a output charging network, an output pre-charge and null propagate network, an evaluation network, a first time varying power supply TVS, a second time varying power supply TVS, and a keeper circuit. Additionally, this disclosure describes an invention that is a time varying power supplythat includes a resonator circuit, an amplitude and power check circuit, one or more overshoot and an undershoot voltage clampsand, exciter circuitsand, and current monitor circuitsand. In addition, the invention includes frequency self tuning with the amplitude and power check circuit, capacitor banksand, and the inductor tap select controller. Amplitude self tuning is provided by the amplitude sample and compare circuit. Further, a phase shift control circuitryis also provided. And, distributed control switching circuitryfor power management is also provided.
