Abstract:
An apparatus for providing a precharge signal to precharge a dynamic logic circuit, the dynamic logic circuit having first and second outputs providing true and complementary data output states when the dynamic logic circuit is in an evaluation state, and providing dual common output states when the dynamic logic circuit is in a precharged state, the apparatus comprising:(a) an output sensing circuit coupled to the dynamic logic circuit, the output sensing circuit for providing an enable signal in response to the true and complementary data output states from the dynamic logic circuit, and for discontinuing the enable signal in response to the common output states from the dynamic logic circuit; and(b) a precharge control circuit for receiving the enable signal and a reset signal, and for providing a precharge signal to the dynamic logic circuit in response to the receipt of the enable signal at the precharge control circuit concurrently with the receipt of the reset signal at the precharge control circuit.
