Abstract
A second main electrode of a first transistor is connected to a first main electrode of a sixth transistor, a second main electrode of the sixth transistor is connected to a first main electrode of a fifth transistor at a first node, a second main electrode of the fifth transistor is connected to a second main electrode of a second transistor, a control electrode of the fifth transistor is connected to the second main electrode of the fifth transistor, a second main electrode of a third transistor is connected to a first main electrode of a fourth transistor at a second node, and a control electrode of the fourth transistor is connected to the control electrode of the fifth transistor. A gain control amplifier controls a voltage supplied to a control electrode of the sixth transistor such that the first node and the second node are equal in voltage.
