(a) Given that the op amp of Fig. P7.6a has the open-loop VTC of Fig. P7.6b, sketch and label vI (t), vO(t), and vE(t) if R1 5 R2 5 10 kV and vI (t) is a 500-Hz triangular wave with peak values of 62 V. Hint: Once you have sketched vO(t), use the VTC to construct the plot of vE(t) point by point. (b) Repeat if the peak values of vI are doubled to 64 V. (c) Repeat if the peaks are doubled once again to 68 V. Hint: trying to force vO(t) above 110 V or below 210 V will cause it to saturate at 110 V or at 210 V, respectively, resulting in a clipped output waveform.
