Electronic Devices & Circuits Power Amplifiers

Biasing a complementary push-pull output stage slightly into conduction changes class B toward class AB mainly to?

AReduce crossover distortion
BEliminate all power dissipation
CForce both devices permanently into cutoff
DCreate negative resistance

Show AnswerHide AnswerReport an error

Correct Answer: A. Reduce crossover distortion

Explanation: Class-AB bias keeps both output devices slightly conducting around zero crossing, reducing the dead zone responsible for crossover distortion.

Reference: Standard analog electronics: class-AB operation
