hello,
hello i am newbie in layout and i have few questions:
1- can i mirror current through (W/L=2.8u/1.4u) to a (W/L=4.2/1.4) as they are 3/2 , i.e. is non-integer ratios good , matching is a necessary here. >>> can any one suggest a common centroid allignment
2- is there something bad in using fingure of W<L ? both in layout "matching" and in operation"physical".
3- how can i match a large # of transistors , like 32 by common centroid , can i match every two together then each group of two ....etc.
thnx
