D 9.32 Consider the differential amplifier of Fig. 9.14 and let the BJT β be very large: (a) What is the largest input common-mode signal that can be applied while the BJTs remain comfortably in the active region with vCB =0? (b) If the available power supply VCC is 2.0 V, what value of IR C should you choose in order to allow a common-mode input signal of ±1.0 V? (c) For the value of IRC found in (b), select values for I and R C. Use the largest possible value for I subject to theconstraint that the base current of each transistor (when I divides equally) should not exceed 2 μA. Let β = 100.
