Current Series Feedback Amplifier

In the current series feedback circuit, a fraction of the output voltage is applied in series with the input voltage through the feedback circuit. This is also known as series-driven series-fed feedback i.e., a series-series circuit. As the feedback circuit is connected in series with the output and the input as well, both the output impedance and the input impedance are increased. The graph compares both input and output magnitude/phases. Voltage gain; decreases Bandwidth: increases input resistance: increase output resistance: increase harmonic distortion and noise: decrease
