19EUEC108-CURRENT SERIES AND SHUNT FEEDBACK AMPLIFIER

The Amplifier is an electronic circuit that is used to increase the strength of a weak input signal in terms of voltage, current, or power. The process of increasing the strength of a weak signal is known as Amplification. One most important constraint during the amplification is that only the magnitude of the signal should increase and there should be no changes in original signal shape. The transistor (BJT, FET) is a major component in an amplifier system. Then, the transistor should be biased to get the desired Q-point. The signal is applied to the amplifier input and output gain is achieved.In this circuit common emitter configuration is used,In Common Emitter Amplifier Configuration, the Emitter of a BJT is common to both the input and output signal
