A fully differential amplifier includes a first single-ended current mirror type fully differential amplifier outputting a first output signal by two stage amplifying a difference between a first input signal and a second input signal and a second single-ended current mirror type fully differential amplifier outputting a second output signal by two stage amplifying a difference between the first input signal and the second input signal. A first tail of the first single-ended current mirror type fully differential amplifier and a second tail of the second single-ended current mirror type fully differential amplifier are connected to each other and the first output signal and the second output signal are differential signals.
