Abstract: Disclosed is an amplifier that includes a first-first (1-1) transistor and a first-second (1-2) transistor to which differential input signals are applied to gate terminals, respectively; a second-first (2-1) transistor including: one end connected to the 1-1 transistor, a gate terminal configured to receive an operating signal, and the other end configured to output one of differential output signals; a second-second (2-2) transistor including: one end connected to the 1-2 transistor, a gate terminal configured to receive the operating signal, and the other end configured to output the other one of the differential output signals; and a switch connected to one end of the 1-1 transistor and one end of the 1-2 transistor. The switch is configured to turn on based on the 1-1 transistor, the 1-2 transistor, the 2-1 transistor, and the 2-2 transistor being turned off.
