WebMay 11, 2024 · Since the output voltage is an analog of a linear change in pulse width if square waves, the class B notion of a crossover notch simply does not apply here. … Crossover distortion is a type of distortion which is caused by switching between devices driving a load. It is most commonly seen in complementary, or "push-pull", Class-B amplifier stages, although it is occasionally seen in other types of circuits as well. The term crossover signifies the "crossing over" of the signal between devices…

Class B Amplifier and the Class-B Transistor Amplifier

WebThe cross over distortion is the problem that occurs when both the transistors are OFF at the same instant, during the transition period. In order to eliminate this, the condition has to be chosen for more than one half cycle. Hence, the other transistor gets into conduction, before the operating transistor switches to cut off state.
