Question 2. For the given circuit: Vcc = +5 V Rci = 10 k12 Rc2= = 10 k12 Vio -OVC2 +5 V AUB1a 91 -OUB2 R= 18.6 k12 Vs Q4 a. With VB1 > -VEE=-5 V = vb2 = 0 V, find Vc1, Vc2, and Vs assuming high ß for all the transistors. b. Find the input common mode range assuming that each BJT requires a minimum Vce 0.3 V to operate in the active mode. c. If, when in operation, the differential amplifier is required to provide an output differential voltage v, that is a sine wave of 1 V peak amplitude, to what value must the maximum input common mode voltage be limited? a
