Abstract
The dynamic circuit includes: a dynamic node; an evaluation circuit for changing the charged state of the dynamic node according to a result of logic evaluation for a plurality of input signals; a control circuit for outputting a control signal of which the logic level changes according to the result of logic evaluation performed by a replica of the evaluation circuit; and an initialization circuit for receiving the control signal from the control circuit and an external control signal, to control start and stop of initialization of the dynamic node according to the control signals.
Claims25
A dynamic circuit comprising:
