Abstract

PURPOSE:To constitute a differential amplifier, which amplifies input signals from two signal input terminals individually and couples these amplified signals and takes out two amplified signals from one output terminal, by a simple circuit. CONSTITUTION:A differential amplifier circuit is constituted by two transistors Tr1 and 2, and input terminals a and b where input signals f1 and f2 are inputted individually are connected to the gate side of these transistors Tr1 and 2. Then, the input side of Tr1 is provided with impedance element 14 which attenuates input signal f2, and the output side of Tr1 is provided with impedance element 15 which attenuates input signal f1. Further, the input side and the output side of Tr2 are provided with impedance elements 17 and 18 which attenuate input signals f1 and f2 respectively, and output ends of impedances 15 and 18 are connected mutually and are connected to output terminal c of the differential amplifier.
