Given the typical values of h_ie = 1 kΩ, h_re = 2 × 10^–4, and A_v = −160 for the input configuration of Fig. 5.185:

a. Determine V_o in terms of V_i.

b. Calculate I_b in terms of V_i.

c. Calculate I_b if h_reV_o is ignored.

d. Determine the percentage difference in I_b using the following equation:

e. Is it a valid approach to ignore the effects of h_reV_o for the typical values employed in this example?
