  • Resonant logic driver circuit
    Patent number: 7098703
    Abstract: An electronic logic driver circuit, for driving a capacitive load between supply potentials for example for use in driving logic circuit elements on or off a chip, is disclosed. The driver circuit comprises switching devices to switch current either to or from two main voltage supply sources and two coupled inductors that act to store energy derived from the voltage sources. In operation, the coupled inductors form an LC resonator with the load such that energy stored in the inductors can be transferred to or from the load to drive a change in the voltage of the load.
