WebMar 29, 2024 · What is the effect of negative feedback on input impedance of voltage shunt and current shunt amplifier? In negative feedback, the feedback energy (voltage or current), is out of phase with the input signal and thus opposes it. Negative feedback reduces gain of the amplifier. It also reduce distortion, noise and instability. WebApr 17, 2024 · Current Shunt. The feedback circuit connected in series for the output and parallel to the input signal is known as a current shunt feedback amplifier. Due to the parallel connection with the input the value of impedance is low at this point. Whereas the output connected in terms of series makes the value of impedance high.
