An amplifier circuit is provided. The amplifier circuit outputs a pair of differential output signals through a first output terminal and a second output terminal. The amplifier circuit includes a first amplifier stage electrically connected to a first node and a second node for amplifying a pair of differential input signals; a second amplifier stage which is electrically connected to the first node and the second node and coupled to the first output terminal and the second output terminal; a first switch, coupled between the first output terminal and a first reference voltage; a second switch, coupled between the second output terminal and the first reference voltage; a third switch, coupled between the first node and the first reference voltage; a fourth switch coupled between the second node and the first reference voltage; and a fifth switch coupled between a second reference voltage and the first amplifier stage.
