WebJul 19, 2024 · A class AB circuit solves the crossover distortion problem by having two (or four) tubes overlap responsibilities. Each tube, or each pair of tubes, carries more than half of the 360-degree signal of the sine wave. In a class AB circuit, two power tubes share the responsibility of conducting the sine wave, similar to class B, but with some overlap. WebThe most commonly used type of power amplifier configuration is the Class A Amplifier. The Class A amplifier is the simplest form of power amplifier that uses a single switching transistor in the standard common emitter circuit configuration as seen previously to produce an inverted output.
