Repeat Problem 5.3 by replacing the circuit to the left of node A (include R_i) by its Thévenin equivalent (see Fig. 5-33). Solve the problem by applying the results of Example 5.4.

Data from Problem 5.3

Let R₁ = 1 kΩ, R₂ = 5 kΩ, and R_i = 50 kΩ in the circuit of Fig. 5-33. Find v₂/v_s for k = 1, 10, 100, 1000, ∞ and compare the results with the values of G⁻ in Table 5-4.

Data from Table 5.4

Data from Example 5.4

In Fig. 5-5, R₁ = 1 kΩ and R₂ = 5 kΩ. 

(a) Find v₂/v_s as a function of the open-loop gain k.

(b) Compute v₂/v_s for k = 100 and 1000 and discuss the results.
