Abstract

A differential amplifier includes an amplification unit and a feedback unit. The amplification unit amplifies a voltage difference between a first input signal and a second input signal and outputs a first output signal and a second output signal. The feedback unit amplifies a voltage difference between a first feedback signal based on the first output signal and a second feedback signal based on the second output signal.
