Summary:In one embodiment, a differential amplifier circuit includes a first input terminal, a second input terminal, a first transistor, a second transistor, a third transistor, a current source, a first output terminal, a second output terminal, a first passive element, and a second passive element. The first (second) transistor has a control terminal connected to the first (second) input terminal. The third transistor has a control terminal. The control terminal is applied predetermined bias voltage. The current source is connected to a first terminal in each of the first transistor, second transistor, and third transistor. The first (second) output terminal is connected to a second terminal of the first (second) transistor. The first (second) passive element is connected between the first (second) input terminal and the first (second) output terminal.
