A receiver is constructed by a signal reception circuit including a first amplifier section adapted to generate a first current in response to a first input signal and a second amplifier section adapted to generate a second current in response to a second input signal, to thereby generate an amplification signal in accordance with a difference between the first and second currents, and a feedback signal generating circuit adapted to generate a feedback signal in accordance with the amplification signal. Driving abilities of the first and second amplifier sections are determined in accordance with the feedback signal.
