ABSTRACT:
The multi-channel amplifier is placed on a common substrate to form a hybrid circuit network, for example a common silicon chip. A source of control voltage is provided connected in common to the base terminals of a pair of transistors, which have their emitters coupled together. The output is taken from the collector of one of the transistors via an emitter-follower transistor. The commonly connected emitters of the pair of transistors are connected through a current supply source forming a third transistor to a source of operating voltage.
