A receiving circuit may include a first amplifying circuit, a second amplifying circuit, a third amplifying circuit, and a feedback circuit. The first amplifying circuit amplifies a first input signal and a second input signal to generate a first amplified signal and a second amplified signal, respectively. The second amplifying circuit amplifies the first amplified signal and the second amplified signal to generate a first preliminary output signal and a second preliminary output signal, respectively. The third amplifying circuit amplifies the first preliminary output signal and the second preliminary output signal to generate a first output signal and a second output signal, respectively. The feedback circuit changes voltage levels of the first amplified signal and the second amplified signal based on a current control signal, the first output signal, and the second output signal.
