Abstract
A dynamic logic circuit having reduced sub-threshold leakage current during standby mode comprises a connection to at least one upper power rail, a connection to a lower power rail, a precharge node, and an output node adapted to be charged to the potential of the upper power rail after a precharge signal is received at the precharge node. A latch on the output node is provided to maintain the potential at the output node, along with at least one input node for receiving at least one evaluation signal to maintain the potential at the output node to the voltage of the upper power rail or reduce the potential at the output node to the potential of the lower power rail. A device is coupled to the output node to set the output node to a potential which minimizes the sub-threshold leakage upon receipt of a standby signal to maintain the potential at the output node at the potential of the upper power rail or at the potential of the lower power rail.
