ABSTRACT:
An electronic circuit for performing clock gating on a clock signal supplied to a clock system using both edges, has a non-inverted/inverted signal selector which has an input connected to an input terminal, is fed with the clock signal through the input terminal, and outputs a first signal obtained by non-inverting or inverting the clock signal in response to a control signal; a signal latch which has an input connected to an output of the non-inverted/inverted signal selector, outputs the inputted first signal as a second signal through an output terminal, and latches a state of the second signal in response to an enable signal inputted through an enable terminal; and an input/output comparator which compares the clock signal and the second signal and outputs the control signal to the non-inverted/inverted signal selector such that the first signal agrees with the second signal.
