    Abstract: A differential amplifier using semiconductor amplifier, which had a characteristic of having complementary conduction, was disclosed. Common electrodes of a 1st and 2nd PNP type input transistor(11,21) having input, common, and output electrodes(base, emitter, collector), were DC conductively coupled reciprocally. The output, input, and common electrodes of 3rd and 4th NPN type transistor(12,22) were DC coupled to the common, the output electrodes of the 1st and 2nd transistor, and the ground, resp.
