hi..

Im designing power amplifier for class B and AB.the problem is i was confused about the circuit.Those expert in power amplifier circuit i need your help.I want to know the exactly circuit with the value for power amplifier class B and AB

Please help me..urgent. :cry:
 

In true class B the positive half of the cycle is provided by one transistor, the negative by another. In between, neither conducts. In class AB there is some conduction in the centre. This helps to reduce crossover distortion as the current drive changes from one side to the other.

thanks:|
