Question:

Let again R₁ = 1 kΩ and R₂ = 5 kΩ in the circuit of Fig. 5-33.

(a) Find v₂/v_s as a function of k and R_i.

(b) Let R_i = 1 kΩ. Find v₂/v₁ for k = 1, 10, 100, 1000, ∞. Repeat for Ri = ∞.

(c) Discuss the effects of Ri and k on the overall gain. Show that, for k = ∞ and R_i ≠ 0, the gain of the amplifier is independent of R_i and is equal to −R₂/R₁. 5 R A R R www Amplifier kv 2
