In the three-stage amplifier circuit of Figure 1, the transistors are identical and matched, Vcc = 10 V, VEE = -10 V, R1 = R2 = 9.1 k2, R3 = R4 = 2.2 k2, and Rs = 10 k12. (a) With V1 = V2 = 0, find the DC collector currents of all the transistors, and the voltages at VB3 and Vout. Assume that ß>>1 and VBE =0.7 V. (b) Calculate the quiescent power dissipation of the circuit. (C) What is the input common-mode range? Assume that an npn transistor saturates when its base voltage is greater than its collector voltage. (d) Which input (V1 or V2) is the non-inverting input? Justify your answer with the appropriate reasoning.
