Abstract
A precharge device is connected to an intermediate precharge node and is arranged to minimize leakage current through the precharge device when deactivated. An input transistor network receiving a plurality of data inputs is connected to the intermediate precharge node. An output inverter is connected to the intermediate precharge node and includes a pair of transistors. A predefined transistor of the pair of transistors is arranged to minimize leakage current through the output inverter. A standby control signal is asserted for a standby mode of the domino circuit and is unasserted for an active mode of the domino circuit. The standby control signal and a clock signal are combined to provide a combined standby clock signal. The combined standby clock signal controls the precharge device. A standby discharge device is connected to the intermediate precharge node and controlled by the standby control signal. The standby discharge device is activated to discharge the intermediate precharge node responsive to the standby control signal being asserted.
