A communication circuit includes a receiver circuit that provides differential communication by using a first transmission path and a second transmission path. The first transmission path transmits a first signal. The second transmission path transmits a second signal. The receiver circuit includes a compensation circuit that compensates for the attenuation of a current when common mode noise is superimposed on the first signal and on the second signal. The compensation circuit includes a first compensation circuit. The first compensation circuit detects an electric current attenuation of the first signal when the common mode noise is superimposed thereon, and compensates for the attenuation thereof by adding the detected electric current attenuation to the second signal.
