|Lesson 10 - Large Signal Amplifier|
Solution to the crossover distortion:
Provide some forward bias for the base emitter junction.
Fig. 10-6: Class AB amplifier
Fig. 10-7: Complementary push pull amplifier
Two complementary transistors are used (NPN + PNP) , so no transformer is needed any more.
Efficiency: between A and B
Application: High power stages in audio and radio-frequency applications.
