For the network of Fig. 4.140, determine:

a. S (I_CO).

---

b. S(V_BE ).

---

c. S (β), using T₁ as the temperature at which the parameter values are specified and β(T₂) as 25% more than β(T₁).

---

d. Determine the net change in I_C if a change in operating conditions results in I_CO increasing from 0.2 μA to 10 μA, V_BE drops from 0.7 V to 0.5 V, and β increases 25%.
