In class AB operation each output device conducts more than half of the input signal cycle. Up to 78% efficiency is possible with class AB designs and cross over distortion is reduced.

The modified circuit now is known as Class AB amplifier circuit. This Class AB amplifier is a circuit made using the characteristics of both Class A and Class B amplifier circuits. From 0V to 0.7V the diodes are biased in conduction state where the transistors have no signal at the base terminal. This solves the crossover distortion problem.

This solves the crossover distortion problem. The diyAudio “diyAB” Class AB Power Amplifier (or “Honey Badger” as we call it at diyAudio HQ) was designed to fill the needs of members that require a high power amplifier with similar capabilities and characteristics to those found most in modern, expensive high end commercial amplifiers. Driving low impedance loads is not a problem A Class-AB audio amplifier involves three stages: Input stage; Voltage Amplification Stage; Output stage. And the design of each stage requires: Basic circuit theory, Transistor-based amplifier design, Filter design, And even a very basic understanding of feedback theory. So, as you can see, a Class AB audio amplifier is not a "how can I design one?" thing. PRACTICAL CLASS AB AMPLIFIERS. The easiest way to build a class-AB audio amplifier is to do so using one of the many readily-available audio ICs of this type.
