Abstract
According to one embodiment, the amplifier circuit includes a first and second differential amplifier. The first differential amplifier includes first and second transistors, a first current source, and a second current source that is configured to supply a current to the first and second transistors via a first switch element. The second differential amplifier includes third and fourth transistors, a third current source, and a fourth current source that is configured to supply a current to the third and fourth transistors via a second switch element. A first signal is input to the first and third transistors. The first switch elements are controlled by third and fourth signals, respectively. The third signal and the fourth signal are complementary.
