Abstract:

General conclusions drawn concerning the effect of feedback on a common emitter amplifier are Series feedback 1 Increases the low frequency input and output impedances of the transistor itself. 2 Decreases the voltage gain, current gain, and gain-bandwidth product of the amplifier. 3 Increases the upper cutoff frequency of the amplifier. 4 Decreases the sensitivity of the amplifier to changes in the transistor parameters Shunt feedback 1 Decreases the low frequency input and output impedances of the transistor itself. 2 Decreases the voltage gain, current gain, and gain-bandwidth product of the amplifier. 3 Increases the upper cutoff frequency of the amplifier. 4 Decreases the sensitivity of the amplifier to changes in the transistor parameters.
