[Prob 3] Signal Conditioning 1. An inverting amplifier has an input resistance of 2kQ. Determine the feedback resistance needed to give a voltage gain of 100

Solution

Voltage gain(AV) =(Feedback Resistance)/(Input Resistance)

AV = 100 given;

so; feedback resistance =(voltage gain * input resistance) = (100 * 2) =200 k ohm
