Abstract
A dynamic NOR circuit includes a pre-charge transistor coupled between a first voltage supply node and a dynamic node to pre-charge the dynamic node. The dynamic NOR circuit includes a first keeper circuit having a first keeper transistor and a second keeper transistor serially coupled between the first voltage supply node and the dynamic node. The dynamic NOR circuit includes a first pull down circuit coupled between the dynamic node and ground. A first input signal is coupled to a gate of a first pull-down transistor in the first pull-down circuit and is also coupled to a gate of the first keeper transistor. A first keeper enable signal is coupled to a gate of the second keeper transistor. Additional keeper circuits and pull down circuits coupled to the dynamic node allow the dynamic NOR structure to handle a plurality of input signals.
