Abstract:
A logic structure comprising:a plurality of logic stages, each logic stage being configured to provide, on at least one output, a corresponding precharge state during a precharge phase, and a logic output state, based on one or more logic inputs, during an evaluation phase that is different from the precharge phase, and at least one precharge control device, wherein at least one of the logic stages is configured to include a precharge device that provides the precharge state, and a logic block that provides the logic output state, and the precharge device and the logic block form a direct series connection between a power source and a ground potential, and the precharge control device is configured to enable the precharge device to provide the precharge state only when the logic inputs are in an inactive state that places the logic block in a non-conductive state; wherein the precharge control device monitors the logic inputs to determine when the logic inputs are in the inactive state.
