amplifier modulates the output of the power supply to make the output signal stronger than the input signal. An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss. The first practical electronic device which could amplify was the

The maximum theoretical power efficiency of a Class A amplifier is between 25% and 50%, depending upon the type of output coupling used. This becomes a problem when an amplifier is used in an audio application because audio is an AC signal and most of the time the input will be closer to zero volts than it will to one of the rails [Qui93].

The function of a power amplifier is to raise the power level of input signal. It is required to deliver a large amount of power and has to handle large current. The characteristics of a power amplifier are as follows − The base of transistor is made thicken to handle large currents. The value of β being (β > 100) high.
