Voc = ww &RCI {R3 २ Rq = = PI KP2 HE = = gru yi RY w ş ERE &RL Q3 (25 pts): Consider the circuit below where B = 120, VA=", VBE(on)=0.7 V and Vce(sat) 0.2 V for both transistors. Take Vcc = 12 V, RI = 67.3 kΩ, R2 = 12.7 kΩ, Rci 10 kΩ, REI = 2 kΩ, R3 = 15 kΩ, R4 = 45 k 2, RE2 = 1.6 k 2, RL 0.25 k 2. Also note that there is a capacitor between the collector of Q1 and the base of Q2. (a) (10 pts) Apply dc analysis and find the collector currents of both transistors. (b) (5 pts) Determine the small signal parameters gm, It, and r, for both transistors (c) (10 pts) Determine the small signal voltage gain
