    It is required to design a class B output stage to deliver an average power of 20 W to an 8-Ω load. The power supply is to be selected such that Vcc is about 5 V greater than the peak output voltage. This avoids transistor saturation and the associated nonlinear distortion, and allows for including short-circuit protection circuitry. (The latter will be discussed in Section 12.6.) Determine the supply voltage required the peak current drawn from each supply, the total...

    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...
