摘要:
A clock gating circuit for generating a clock enable signal with respect to a clock input signal and a logic enable signal includes: a first plurality of transistors coupled in series between a power supply and ground, for receiving at least the logic enable signal and generating a first output; a second plurality of transistor coupled in series between the power supply and ground, for receiving at least the first output and generating a second output; a third plurality of transistors coupled in series between the power supply and ground, for receiving at least the second output and an inverted second output; and an AND gate circuit, for receiving the second output and generating the clock enable signal.
