Abstract
An amplifier circuit includes a first transistor, through which a first input current is made to flow between the drain and the source; a second transistor, through which a second input current is made to flow between the drain and the source; a first-1 current source, which supplies a predetermined current to the gate of the first transistor; a first-2 current source, which supplies a predetermined current to the gate of the second transistor; a pair of adjustable resistors, which are connected in series between the gate of the first transistor and the gate of the second transistor; a connecting path, which connects a connection point of the pair of adjustable resistors to the drain of the first transistor; and a second current source, which supplies a current to the drain of the second transistor.
