Problem II: (20 Mark, a) 6, b) 6, and c) 8 Marks): In the circuit shown in Figure 2 below, let Vcc= 5 V, RE = 0.2 k2, Rc= 1

k, B = 150 & VBE (on) = 0.7 V. Design a bias-stable circuit such that the operating point also called Q-point is in the center of the load line (VCEQ= 2.5 V). a) Convert the common emitter circuit with a common emitter resistor to its The venin equivalent circuit, show and label the circuit b) Solve for VTH and RTH c) Solve for Ri and R2
