Single stage pulsed domino circuit for driving cascaded skewed static logic circuits
Abstract:
A complementary metal oxide semiconductor (CMOS) low-power, high speed logic circuit consisting of a cascaded chain of stages. The first stage is a pulsed domino logic circuit having one or more logic signal inputs for receiving data signals, and a timing input for receiving a clocking pulse that conditions the input pulse domino stage for evaluation during a brief window of time. The output of the pulsed domino circuit is connected to a chain of series-connected skewed static logic gates, each having the channel sizes of its pull-up and pull-down transistors ratioed to a produce, from gate-to-gate in the static logic chain, alternating fast high-to-low and low-to-high transitions for the information carrying leading edge of said input data signals. The use of a pulsed domino first stage driving a chain of skewed logic static gates reduces power consumption but retains the speed of conventional domino logic circuits.
