Question 4 (20 marks) The transistor of the circuit shown in Figure 4 , has \( \beta=100 \). Ignore the Early voltage. a) Find DC bias values of \( V_{E C C} \) and Ica. ( 8 marks) b) Use the \( \pi \) model of the transistor and determine the small signal voltage gain \( \left(v_{0} / v_{\text {sig }}\right) \). (12 marks) Figure 4.
