Problem 8.51

In this problem we explore the trade-off between input common-mode range and differential gain in the design of the bipolar BJT. Consider the bipolar differential amplifier in Fig. 8.15 with the input voltages(a) Bearing in mind that for a BJT to remain in the active mode, should not exceed 0.4 V, show that when has a peak , the maximum input common-mode voltage is given by(b) For the case V and mV, use the relationship above to determine for the case V/V. Also find the peak output signal and the required value of . Now if the power dissipation in the circuit is to be limited to 5 mW in the quiescent state (i.e., with vid = 0), find I and (Remember to include the power drawn from the negative power supply V.) (c) If is to be 0 V, and all other conditions remain the same, what gain is achievable?
