Class B push pull amplifier are the most commonly used circuit for amplification purpose due to its higher efficiency. A push pull amplifier is an amplifier which has an output stage that can drive a current in either direction through Power amplifier circuits maybe classified as A, B, AB and C for analog based designs and
Electronics Tutorial about the Class AB Amplifier Circuit that is forward biased to eliminate the crossover distortion that are found in Class B designs. A Class AB amplifier can be made from a standard Class B push–pull stage by biasing both switching transistors into slight conduction, even when no input signal is present.

Experiment 6. 1. PUSH-PULL AMPLIFIER. Objective: To demonstrate the use of the capacitor-coupled complementary push-pull class-AB power amplifier. Discussion: Figure 2 shows how a Preliminary Exp. Step1 : Construct the circuit in Figure 1 and find the IC(SAT) (VCC=10 V). Preliminary Exp. Step2 : Fix the VCC at 5
2 May 2012 Circuit diagram and working of push pull amplifier. ClassA, Class B, Class C configurations. Circuit diagram and theory. Cross over distortion.
amplifier over a class A amplifier is that either one is more efficient than a class A amplifier; you can get more output power for a given amount of input power. A disadvantage of class B or class AB is that it is more difficult to implement the circuit in order to get a linear reproduction of the input waveform. The term push-pull
