In a class- AB amplifier, the transistors are biased slightly above cutoff to avoid
A)clipping the peaks of signals
B)low efficiency
C)loading problems
D)crossover distortion

Question

Quizplus · Accepted Answer

Class-AB amplifiers are biased slightly above cutoff to avoid crossover distortion, which occurs when the output transistors switch from the off to the on state during the signal cycle. This biasing method helps in ensuring a smoother transition between the active devices, reducing distortion at the output.
