ADVANTAGES OF CLASS A PUSH PULL AMPLIFIER
→Because of the absence of even harmonics in the output it gives more output per active devices for a given amount of distortion or less distortion for a given output per transistor.
→Eliminates Non-linear Distortion, that may arise due to the curvature of transformer magnetization curve.
→Lower ripple Voltage
DISADVANTAGES OF CLASS A PUSH-PULL AMPLIFIERThe drawbacks of push-pull amplifiers are:-
→Requirement of two identical or matched transistors.
→It need the use of driver stage to furnish two equal and opposite voltages at the input
→It requires Bulky and expensive Transformers
