Transistor Amplifiers – Class A, AB, B, & C Circuits
This electronics video tutorial provides a basic introduction into the Class A, AB, B, and C transistor amplifiers. The class A amplifier is the common emitter amplifier which uses a single NPN transistor. The Class B amplifier using two complementary NPN and PNP transistors and yields a higher amplifier efficiency. The Class AB amplifier uses two diodes to eliminate the crossover distortion that’s present in the Class B amplifier. The Class C amplifier is a tuned amplifier with a high efficiency but with extensive distortion.
