What class amp is used as a push-pull circuit?

The use of a Class B amplifier in a push-pull configuration is significant due to its efficiency and linearity in handling audio signals. In a push-pull circuit, two transistors (either bipolar junction transistors or field-effect transistors) are employed, with one conducting during the positive half of the input signal's cycle and the other during the negative half. This arrangement allows for improved efficiency compared to Class A amplifiers, as Class B amplifiers reduce power consumption by only conducting half the time.

This method also minimizes distortion, especially when handling large signals, making it ideal for audio amplification purposes in various applications. The push-pull setup effectively cancels out even-order harmonics, which contributes to a cleaner output signal. Therefore, the Class B amplifier's architecture enables it to balance performance and efficiency, which is crucial in many audio electronic devices.
