Why is offset always referred to the input?
Answer: D
Referring an imperfection to the input divides out the gain, so two amplifiers of different gain can be compared on the same footing. It is actually harder to measure there, which is why it is computed from an output measurement. The mismatch does occur at the input but that is not why the convention exists. Referring an error to the input is a general technique that works because everything at the input is multiplied by the same gain as the signal. A limit that survives making every external component ideal is an intrinsic one, and worth knowing for that reason.
