Abstract: A differential signaling circuit is provided. The differential signaling circuit includes: a differential amplifier configured to generate differential signals; a first signal path circuit; a second signal path circuit; a phase control circuit configured to receive the differential signals having a common phase, output DC signals having a common level in a first operating period, and transmit the differential signals to the first signal path circuit and the second signal path circuit, respectively, in a second operating period; and a duty ratio correction circuit connected between the first signal path circuit and the second signal path circuit, and configured to control duty ratios of the differential signals to be equal to each other in the second operating period.
