Abstract
A first transistor having a base or a gate supplied with a high-frequency signal through a capacitor, and supplied with a bias current through a resistive element, a second transistor having a base or a gate connected to an emitter or a source of the first transistor, and a collector or a drain connected to an output terminal, and a third transistor having a collector or a drain connected to the base or the gate of the first transistor, and an emitter or a source connected to reference potential are provided, and the third transistor is provided such that a current flowing through the collector or the drain of the third transistor increases when a current flowing through the collector or the drain of the second transistor increases.
