(b) Identify the Op Amp configuration in the figure.
(12 marks)
The Op Amp has a feedback resistor R2=4M and R1=400k. It's open loop input impedance is 10M, open loop output impedance is 24, and open-loop gain is 250,000. When it's in a closed loop, as in the figure, calculate:
i. The gain
ii. The attenuation factor
iii. The input impedance
iv. The output impedance
( b ) Identify the Op Amp configuration in the
