Abstract
A phase comparison circuit includes: a first flip-flop configured to receive a data signal and a clock signal; a second flip-flop configured to receive an output signal of the first flip-flop and a signal that is an inversion of logic of the clock signal; a delay circuit configured to give delay time to the data signal, in which the delay time is equal to or longer than signal delay time from a clock terminal of the first flip-flop to a Q output terminal of the first flip-flop; a first exclusive OR circuit configured to receive an output signal of the delay circuit and the output signal of the first flip-flop; and a second exclusive OR circuit configured to receive the output signal of the first flip-flop and an output signal of the second flip-flop.
