An amplifier including a first transistor and second and third transistors forming a complementary pair. The first and second transistors are of the same type. An input signal is applied to the emitter of the first transistor and a constant current to its collector, which is also connected to the base of the second transistor. The bases of the first and third transistors are connected while the emitters of the second and third transistors are commoned and connected to a load. A power supply is connected to the collectors of the second and third transistors.
