ABSTRACT:
A differential amplifier comprises first and second transistors which are differentially coupled. The amplifier includes a load connected with collectors of the first and second transistors, wherein the base of a third transistor is connected to the collector of the first transistor. The emitter-collector path of the third transistor is connected between the collector of the second transistor and the load. An output signal is supplied from the collector of the first transistor.
