feedback amplifiers

The effect of current shunt feedback in an amplifier is to

Voltage series feedback (also called series-shunt feedback) results in

An amplifier without feedback has a voltage gain of 50, input Resistance of 1 k$$\Omega $$ and output Resistance of 2.5 k$$\Omega $$ . The input Resistance of the current-shunt neg...

In a negative feedback amplifier using voltage - Series (i.e., voltage - sampling, series mixing) feedback

An amplifier has an open loop gain of 100, an input impedance of 1 k$$_\Omega $$, and an output impedance of 100 $$_\Omega $$ . A feedback network with a feedback factor of 0.99 is...
