Plot the closed-loop frequency response V₃/V_ac in Fig. 15-34 (a) for f as it varies from 1 MHz to 1 GHz, using the subcircuit model shown in Fig. 15-34(b). Compare with the open-loop frequency response obtained in Problem 15.12. The feedback resistor is 1 kΩ < R_f < 801 kΩ, incremented in steps of 200 kΩ.
