WebMar 30, 2024 · Crossover distortion is the term given to a type of distortion that occurs in push-pull class AB or class B amplifiers. It happens during the time when one side of the output stage shuts off, and the other turns on. If there is a difference in timing of on and off of two stages of the transistor, cross over distortion occurs. WebDec 11, 2024 · A very profound limitation of this class is the crossover distortion. As two devices provides each half of the sinusoidal waves which are combined and joined across the output, there is a mismatch (cross over) in the region, where two halves are combined. This is because when one device complete the half cycle, the other one needs to provide ... WebThis video discusses the basics of crossover distortion.
