Common centroid
Hi All,
I know that common centroid method has been used for quite long time in order to improve matching.
I never used common centroid or interdigitate methods for matching. I use large area devices and place matching devices close to each other, and I never had mismatch problems. One of my colleague claims that for deep submicron process the common centroid method is obsolete and anyway not sutible for high speed circuits.
Please share with me your thoughts...
