Experiment 6: Op-Amp Circuits I A. Inverting Amplifier The inverting amplifier is the most popular op-amp circuit. The basic disadvantage of this circuit is that its input impedance is low (equal to the value of R 1 in the circuit shown above.) Q1: Why is a low input impedance considered a disadvantage ? Q2: Complete Table A-1 in In-Lab Rport, and verifyexperimentaly that , ܸ ൌെ ܸ Use an 1000 Hz sinusoidal input voltage with 200 mV peak-to-peak. Q3: Determine the bandwidth of the inverting op-amp. The bandwidth in this case is equal to the frequency at which the magnitude of the gain V O /V I drops to 1/√2 of its low frequency value (which is, theoretically, R 2 /R 1 ). For R
