<P>PROBLEM TO BE SOLVED: To provide a receiving circuit that can accurately detect a clock signal having a single phase and a small amplitude. <P>SOLUTION: The receiving circuit includes: an AC coupling circuit 22 for AC-coupling a first end and a second end; a low pass filter circuit 23, 25 for low-pass-filtering a second signal appearing at the second end in response to a first signal applied to the first end to generate a third signal; and a comparator 21 for inputting the second signal and third signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
