ABSTRACT:
A semiconductor integrated circuit includes a flip-flop circuit, a capacitive element, and a switch circuit. The switch circuit includes a first switch circuit which couples the capacitive element to two nodes of the flip-flop circuit at a first timing, and a second switch circuit which short-circuits ends of the capacitive element connected to the two nodes at a second timing different from the first timing.
