Abstract
A novel precharge circuit is provided for dynamic CMOS logic circuits which are immune to leakage currents and reduce overall power consumption. The circuit comprises a precharge transistor for precharging a node to a high voltage level indicting a first logic state during a standby mode. Thereafter, during an active mode, the node may or may not be discharged by connected logic circuitry. If the node is discharged, then an additional transistor is provided to inhibit the precharging of the already charged node during a subsequent standby mode. Similarly, if the node is not discharged, a small keeper transistor is provided to keep the node at a fully precharged level.
