The invention proposes a push-pull balanced current amplifier. In addition, the amplifier comprises nineteenth, twenties, twenty first, twenty second transistors, with first terminals of first and second current sources are connected to bases and collectors of first and second transistor correspondingly, as well as to bases of fifth and sixth transistors correspondingly, as well as to bases and collectors of nineteenth and twenties transistors correspondingly, as well as to bases and collectors of ninth and tenth transistors correspondingly, as well as to bases and collectors of twenty first and twenty second transistors correspondingly, as well as to bases and collectors of eleventh and twelfth transistors correspondingly; second terminals of first and second current sources are connected to bases and collectors third and fourth transistors correspondingly, as well as to bases of seventh and eighth transistors correspondingly, as well as to bases twenty first and twenty second transistors correspondingly; emitters of twenty first and twenty second transistors are connected to drains of fourth and third transistors, correspondingly; emitter of first, fifth, ninth, fifteenth, nineteenth transistors, as well as collector of seventeen transistors are connected to positive power distribution bus; emitters of second, sixth, tenth, sixteenth, twenties transistors, as well as collector of eighteenth transistor is connected to negative power distribution bus. |
