= = Q3 (30 Marks). Given the circuit configuration below, where Tį and T2, T3 and T4 are identical (where early effect can be ignored), VBE 0.7V, The1 = Pbe2 = 2.5k12, B1 = B2 = 50, find out (1) Quiescent emitter current (DC emitter current) of T1 and T2, (2) Small-signal (AC) voltage gain, (3) Small-signal voltage gain if a load resistor with the same value as R3 is introduced, where one terminal of the load resistor is attached to the collector side of T1, and the other terminal is attached to the ground. Vcc=15V R3 = 10kΩ R4=10kΩ uo o R1=10kΩ R2=10kΩ T1 T2 ui R5=12k T3 T4 Vee = -15V
