Apparatus for voltage regulation and recovery of signal termination energy
First Claim
1. An apparatus for regulating the intermediate voltage planes of a system relative to an upper power supply voltage plane, the apparatus transferring energy, which is normally wasted or dissipated during the termination of an electrical signal, from an intermediate voltage plane to an upper power supply voltage plane, the apparatus comprising:
- a control circuit operable to accept a plurality of input signals and to produce a desired output signal;
an energy store and an energy transfer mechanism, the energy store and the energy transfer mechanism being operable to allow the control circuit to control the timing and amount of any transfer of energy from the energy store;
a feedback circuit coupled to the upper power supply voltage plane and providing input to the control circuit; and
a voltage inverting circuit coupled to the intermediate voltage plane and providing input to the control circuit.

Abstract
An apparatus for regulating the signal termination voltage planes of a system, the signal termination voltage planes having a voltage which is between, or intermediate to, the system'"'"'s upper and lower power supply voltage planes, and for recovering signal termination energy, which is normally dissipated or otherwise wasted, and for transferring the recovered energy to the system'"'"'s upper power supply voltage plane, or power bus, for reuse.
