A receiving circuit is provided that can accurately detect a clock signal that has a single phase and a small amplitude. A receiving circuit includes an AC coupled circuit 22 that creates an AC coupling between a first end and a second end, a low-pass filter circuit 23, 25 that produces a third signal by applying a low-pass filtering on a second signal that is produced on the second end in response to a first signal that is applied to the first end, and a comparator 21 that inputs the second signal and the third signal. |
