  • Single rail domino logic for four-phase clocking scheme
    Patent number: 6265899
    Abstract: A single rail domino logic circuit using a four-phase clocking scheme. A stacked PMOS pair provides a quarter clock cycle precharge time. The quarter clock cycle precharge time allows for placement of an additional inverter in the output signal path to form both an output signal and a complement of the output signal for use in subsequent logic stages.
