Abstract
Provided is a differential amplifier including: an operational amplifier (OP AMP) having an inverting input, a non-inverting input, an inverting output, and a non-inverting output, a first feedback capacitor connected to the non-inverting input and the inverting output. A second feedback capacitor connected to the inverting input and the non-inverting output, a first four-terminal transistor connected to the non-inverting input and the inverting output. A second four-terminal transistor connected to the inverting input and the non-inverting output. One of source and drain of the first transistor and a gate thereof are connected to the inverting output, the other one of the source and drain and a bulk terminal are connected to the non-inverting input, one of source and drain of the second transistor and a gate thereof are connected to the non-inverting output, and the other one of the source and drain terminals and a bulk terminal are connected to the inverting input.
