Chapter 2, Problem 2.66(choose chapter or problem)
For the difference amplifier of Fig. 2.16, show that if each resistor has a tolerance of 100 % (i.e., for, say, a 5% resistor, = 0.05) then the worst-case CMRR is given approximately by where K is the nominal (ideal) value of the ratios and Calculate the value of worst-case CMRR for an amplifier designed to have a differential gain of ideally 100 V/V, assuming that the op amp is ideal and that 1% resistors are used.
