Comparing the two columns in Table 5-6 we see that the smaller Ri reduces the overall gain G . However, as the open-loop gain k increases, the e ect of Ri is diminished. As k becomes very large, v2 =v1 approaches 5 unless Ri 0.

Because of high gain, saturation occurs quickly at jv2 j 105 jvd j 10 V We may ignore the linear interval and write  v2 where vd v v sin t (V). 10 V 10 V vd > 0 vd < 0 or jvd j 10 4 V
One cycle of the output is given by  10 V 0<t< v2 10 V  < t < 2
For a more exact v2 , we use the transfer characteristic of the op amp in Fig. 5-7. 8 < 10 vd < 10 4 V 5 4 v2 10 vd 10 < vd < 10 4 V : 10 vd > 10 4 V Saturation begins at jvd j j sin tj 10 4 V. output v2 is then given by v2 v2 v2 v2 Since this is a very small range, we may replace sin t by t. 10 4 10 4  10 4  10 4 < t < 10 4 s < t <  10 4 s < t <  10 4 s < t < 2 10 4 s The
105 t 10 105 t  10
To appreciate the insigni cance of error in ignoring the linear range, note that during one period of 2 s the interval of linear operation is only 4 10 4 s, which gives a ratio of 64 10 6 .
Repeat Problem 5.6 for v sin 2t (V) and v 0:5 V.
The output voltage is v2 10 V when v > v when v < v Therefore, one
v2 10 V Switching occurs when sin 2t 1=2. cycle of v2 is given by
This happens at t 1=12, 5/12, 13/12, and so on. 1=12 < t < 5=12 s 5=12 < t < 13=12 s
