Design of high performance class B push pull amplifier

Abstract

Class B push pull amplifier are the most commonly used circuit for amplification purpose due to its higher efficiency. In spite of having a very high efficiency, crossover distortion is one which severely affects the performance of Class B amplifier. It can be reduced by the use of op-amp as a negative feedback op-amp. The op-amp can also be used a buffer. The use of diode creates a dead band in the output voltage. The heating effect in the diode is reduced by the use of temperature compensation feedback resistor.
