Write the formula for closed loop voltage gain of inverting amplifier with feedback using open loop voltage gain and gain of feedback circuit.
Write the formula for closed loop voltage gain of inverting amplifier with feedback using open loop voltage gain and gain of feedback circuit. Correct Answer AF= -B/(1+AB)
The closed loop voltage gain of the amplifier is AF= -Ak/(1+AB), where k is a voltage attenuation factor. In addition to phase inversion, AF is k times the closed loop gain of the non-inverting amplifier where k<1.
