Disclosed is a push-pull balanced current amplifier where introduction into a circuit of new connections and twenty ninth, thirtieth, thirty first, thirty second bipolar transistors, as well as third and fourth current sources increases accuracy of operation and amplification coefficient. Introduction of twenty first and twenty second bipolar transistors as intermediate amplification stages increases circuit amplification coefficient. The first and second current sources and first, second, fifth and six bipolar transistors form a DC mode setting circuit. The third and fourth transistors form an input amplification stage. A two-way current reflector is formed using seventeenth, eighteenth, twenty third and twenty fourth bipolar transistors with broken commutators. Said reflector and current compensators built on third, seventh, ninth and fourth, eighth, tenth bipolar transistors set DC mode for the input and intermediate stages. A balancing capacitor compensates frequency response and prevents the circuit generating. |
