Abstract
The differential amplifying circuit includes a first bias resistor having a variable resistance and connected between the first input terminal and the reference voltage node. The differential amplifying circuit includes a second bias resistor having a variable resistance and connected between the second input terminal and the reference voltage node. The differential amplifying circuit includes a controlling circuit that controls the resistance of the first bias resistor and the resistance of the second bias resistor in synchronization with each other.
