SUMMARY
The discussion focuses on the derivation of equations 10-8 and 10-9 related to the common mode gain of differential amplifiers. It emphasizes that for a differential amplifier to function correctly, the ratio R2'/R1' must equal R2/R1, resulting in a difference mode gain of R2/R1 and a common mode gain of 0. Additionally, the sensitivity analysis involves introducing an error term to a resistor, such as R2 → R2 + ΔR, to observe discrepancies in the common mode gain calculations.
