The last stage of operational Amplifier is a power amplifier. Class B is a good choice for the power amplifier. However, class B suffer from crossover distortion. Several methods are used to correct this non linearity as was discussed in the lecture (class AB). One of this method is the use of VBE multiplier. Design the output of an operational amplifier using class AB that employ VBE multiplier. For temperature stability RE can be used for the NPN and PNP...
