Abstract:
A dynamic logic circuit includes an N channel transistor stack between a dynamic node and a first power terminal for receiving a plurality of logic signals. A first clock transistor is coupled between a second power terminal and the dynamic node for receiving a clock signal. A second clock transistor is in series with the N channel stack, between the dynamic node and a second power terminal, and for receiving the clock signal. An inverter circuit has an input coupled to the dynamic node and an output. A keeper transistor has a control electrode coupled to the output of the inverter circuit, a first current electrode coupled to the dynamic node, and a second current electrode. A plurality of P channel transistors, which are coupled in parallel, are coupled between the keeper transistor and the second power terminal and are for receiving the plurality of logic signals.
