An emphasis circuit includes: an applying circuit to add an emphasis signal to an input differential signal; a feedback path to feed back a differential output of the applying unit; a comparing circuit to compare a direct current component level of a positive phase signal and of a negative phase signal of the differential signal; a direct current component level controlling circuit to control a direct current component level of at least one of the positive phase signal and the negative phase signal; a delay unit circuit to add a delay to at least one of the fed-backed differential signal to generate the emphasis signal and inputs the emphasis signal into the applying unit; and a dummy load coupled to a positive phase signal output or a negative phase signal output of the applying unit. |
