Plot the output voltage of the operational-amplifier circuit of Problem 7.5 and shown in Figure 7.40(b) for C1 = 3 mF, C2 = 5 mF, R1 = 100 X, R2 = 85 X, and vi = 110 V using Simulink®. The resistors are nonlinear with their saturation limits being +70 V and −50 V.
Using the complex impedance approach, find the transfer function Vo(s)/Vi(s) of the operational amplifier system shown in Figure 7.40
(a) and demonstrate that the system is a non-inverting amplifier. Apply the result to calculate the transfer function of the system of Figure 7.40(b).
