Abstract
A signal selection circuit, for example, a high value selection circuit, has two unit circuit elements each including of an amplifier with an inverted input terminal and a non-inverted input terminal, and a transistor of which the base is connected to the output terminal of the amplifier and of which the emitter is connected to the inverted input terminal of the amplifier. Input signals are applied to the non-inverted input terminal of the amplifier. A constant-current circuit is connected to the emitter of npn-type transistor in each of the unit circuit elements, and is further connected to a first power-source terminal. A second power-source terminal is connected to the collector of each of the transistors.
