Figure P7.26 shows how the feedback triple of Fig. 7.23 can be confi gured for series-series operation. Assuming the parameters of Example 7.10 (R1 5 1.0 kV, R2 5 3.0 kV, and R3 5 R4 5 R5 5 10 kV,...

Figure P7.26 shows how the feedback triple of Fig. 7.23 can be confi gured for series-series operation. Assuming the parameters of Example 7.10 (R1 5 1.0 kV, R2 5 3.0 kV, and R3 5 R4 5 R5 5 10 kV, along with gm 5 1y(25 V), r5 5 kV, and ro 5 ` for all BJTs), estimate Ri , Ro, and the unloaded gain Asc 5 ioyvi . How does the loop gain compare with that of Example 7.10? Comment.
