ABSTRACT:
A balancing amplifier comprising a pair of transistors arranged as a differential amplifier and a negative feedback network including a transistor voltage follower as a part of the load circuit of each transistor of the pair of transistors. Owing to the negative feedback network high level signals can be balanced. The amplifier provides output signals in phase opposition from a single-ended input signal.
