ABSTRACT:
Regarding N-channel first transistor and a P-channel second transistor, their first terminals are connected to each other and their second terminals are connected to each other. Regarding third transistor and a fourth transistor, their first terminals are also connected to each other and their second terminals are also connected to each other. For the first transistor through the fourth transistor, a first capacitor through a fourth capacitor used for coupling are provided. A first impedance element through a fourth impedance element are provided in a path where a bias voltage is applied to the first transistor through the fourth transistor. A fifth capacitor is provided between the first terminals of the first-fourth transistors and a first input terminal. A fifth impedance element and a sixth impedance element are provided as differential pair loads.
