Shunt-shunt feedback amplifier

WebA voltage shunt feedback is a shunt-derived, shunt-fed feedback connection. Here, a fraction of the output voltage is supplied in parallel with the in put voltage through the feedback network. The feedback signal If is proportional to the output voltage Vo. WebThe introduction of feedback causes a big difference in how the feedback amplifier behaves. Starting with the same initial three-stage amplifier, a Shunt input/Shunt output feedback arrangement shown in Figure 1 results in a transR amplifier that can be viewed as an almost ideal voltage source driving the load.
