Patent ID: 7830178

Claim:
A dynamic circuit comprising: a chargeable dynamic node; an evaluation circuit for performing logic evaluation for a plurality of input signals and discharging the dynamic node based on an evaluation result; a control circuit having a replica circuit of a part of the evaluation circuit or the same of the evaluation circuit and outputting a first control signal of which the logic level changes according to a result of logic evaluation for a part of the plurality of input signals or all of the plurality of input signals performed by the replica circuit; and an initialization circuit for receiving the first control signal from the control circuit and a second control signal from outside, and starting precharge of the dynamic node if the second control signal shifts from a first logic level to a second logic level and stopping the precharge of the dynamic node if the first control signal shifts from a first logic level to a second logic level, wherein the evaluation circuit is directly connected to the chargeable dynamic node.
