Chapter 2, Problem 2.65(choose chapter or problem)
For the difference amplifier shown in Fig. P2.62, let all the resistors be 10 k x%. Find an expression for the worst-case common-mode gain that results. Evaluate this for x = 0.1, 1, and 5. Also, evaluate the resulting CMRR in each case. Neglect the effect of resistor tolerances on Ad .
