Resonant logic and the implementation of low power digital integrated circuits

摘要

A method and apparatus for operating logic circuitry with recycled energy. Logic circuitry is used which has a node for storing energy and a return node that is connected to energy storage circuitry. The logic circuitry operates, using energy stored on the node, to determine a logic output based on a logic input during a first phase. The energy storage circuitry capture a portion of the stored energy during the operation of the logic circuitry and transfers a portion of the captured energy back to the node during a second phase. The energy storage circuitry oscillates with a determinable period and is tunable so that its oscillations can be synchronized to a clock.
