Двотактний симетричний підсилювач струму

Abstract

A push-pull balanced current amplifier comprises a current source, a feedback resistor, a balancing capacitor, positive and negative power distribution buses, a zero bus, twenty four transistors. Additionally, twenty fifth, twenty sixth, twenty seventh, twenty eight transistors are incorporated. Collectors of thirteenth and fourteenth transistors are connected to collectors of seventh and eighth transistors, as well as to bases of nineteenth and twentieth transistors, correspondingly. Emitters of nineteenth and twentieth transistors are connected to bases of twenty seventh and twenty eighth transistors correspondingly, as well as to collectors of seventeenth and eighteenth transistors correspondingly. Collectors of nineteenth and twentieth transistors are connected to bases and collectors of twenty first and twenty second transistors, as well to bases of eleventh and twelfth transistors, correspondingly. Emitters of twenty first and twenty second transistors are united and connected to the zero bus. Emitters of twenty seventh and twenty eighth transistors are connected to buses and collectors of twenty fifth and twenty sixth transistors, correspondingly, as well as to buses of seventeenth and eighteenth transistors, correspondingly. Collectors of twenty seventh and twenty eighth transistors are connected to buses and collectors of fifteenth and sixteenth transistors, correspondingly, as well as to buses of twenty third and twenty fourth transistors correspondingly. Emitters of fifteenth and sixteenth transistors are united. Emitters of first, third, thirteenth, ninth, seventeenth, twenty fifth transistors, as well collectors of twenty third transistor are connected the positive distribution bus. Emitters of second, fourth, fourteenth, tenth, eighteenth, twenty sixth transistors, as well as collector of twenty fourth transistor are connected to the negative power distribution bus.
