The fully differential amplifier of the second single ended current mirror type outputs a second output signal by amplifying the difference between the first input signal and the second input signal in the two-stage amplification manner. A first tail of the fully differential amplifier of the first single ended current mirror type is connected to a second tail of the fully differential amplifier of the second single ended current mirror type.
