So let's say I have a perfectly symmetrical Voltage transfer function curve for my CMOS inverter. The curve looks like this:
The question is, how would this curve change if the size of the NMOS transistor was reduced.
My answer: The curve would still be symmetric but would start shifting right.
But I just know that from my textbook, I don't understand WHY the curve would shift right.
So why exactly will it maintain symmetry and shift right?
