Abstract: In a semiconductor differential amplifier comprising a differential pair of npn transistors having the emitters connected to the emitter of lateral transistors, the bases supplied with an input signal, and the collectors connected in common to one terminal of the voltage source so as to derive the output signal from the collector of the lateral transistor, the emitter voltage of each of the differential pair transistors is applied to the common base of the pnp lateral transistors through a constant voltage element consisting of a transistor or a diode. Therefore, the voltage applied between the base and the substrate of the lateral transistor is reduced and hence the tolerance to the reverse breakdown voltage is increased and simplification of the circuit structure becomes possible. Further, a sink current path is provided between the base of the pnp lateral transistor and the other terminal of the voltage source to allow a stabilized bias current to flow through the differential amplifier.
