Set the Gain of an Opamp Accurately Using a Potentiometer
I want to set the gain of an opamp accurately using an potentiometer, with low thermal drift and good long-term stability. From what I've read, there are three basic ways of doing it, but none of them ...

Estimating gain tolerance
Estimate the gain tolerance (+/- X%) of the non-inverting amplifier in Fig. 3 assuming that the tolerance is solely determined by the errors in the resistor values. Only resistors involved in the gain ...

Differential amplifier inaccuracy resistors exercise to calculate CMRR
The common mode gain for a differential amplifier in the general case is:
$${V_o \over V_c }={ R_1R_4-R_2R_3 \over R_1(R_3 + R_4) }\tag{1}$$
simulate this circuit – Schematic created using ...
