Statement I: A differential input steers current from one device to the other.
Statement II: A common-mode input steers current from one device to the other.
In the light of the above statements, choose the correct answer.
Answer: A
The first is true and the second is false: a common-mode input moves both devices together, and with a good tail source the total current is unchanged and nothing is steered. The distinction is the whole of the pair's behaviour: differential inputs redistribute a fixed current, common-mode inputs try to change it and are prevented from doing so. Every property of the stage follows from those two responses.
