Class AB operation is often used in power large signal amplifiers in order to_________?
Correct answer: C. overcome a crossover distortion
- A. get maximum efficiency
- B. remove even harmonics
- C. overcome a crossover distortion
- D. reducing collector dissipation
Explanation
Class B amplifiers suffer crossover distortion near zero current, where neither transistor conducts properly. Class AB applies a small forward bias so both devices conduct slightly and the crossover gap is reduced.
