Dynamic logic circuit
Abstract:
A dynamic logic circuit includes an N channel transistor stack between a dynamic node and a first power supply terminal for receiving a plurality of logic signals. A P channel clock transistor is coupled between a second power supply terminal and the dynamic node is for receiving a clock signal. An N channel clock transistor is in series with the N channel stack and is between the dynamic node and the first power supply terminal is for receiving the clock signal. A keeper transistor has a first current electrode coupled to the dynamic node, a second current electrode coupled to a second power supply terminal, and a control electrode. A static logic circuit has an output for providing an output responsive to a state of the logic signals. The output is coupled to the control electrode of the keeper transistor.
