Hi, all readers
how can i know process dependent parameters like Aw,Avth in 0.35 micron.
i want to resize transistors of my circuit to decrease offfset of my opamp but i need
mentioned parameters.
thanks.
In order to decrease the offset you don't need to know the absolute values of the mismatch parameters: In 1st order approximation, mismatch ~ 1/√W*L .
So if you increase both W & L by a factor of 3 , the offset mismatch should be reduced by this very factor - best possible tight, mixed & common centroid layout symmetry taken for granted, of course.
