push-pull amplifier
  • An amplification circuit incorporating two identical signal branches which each operate in phase opposition. The active devices may be two transistors or two tubes, and their outputs each comprise half of the combined amplified output. Such an arrangement provides for cancellation of even harmonics, which reduces distortion. Such amplifiers are frequently utilized for class A, class AB, or class B amplification, such as that used in audio high-fidelity systems.
