Analog CMOS Layout Individual Finger Width Sizing
Hello,
When doing Analog CMOS Layout, what is the maximum finger individual width that should be used for fingers in MOS layouts ?
I was told that a maximum size should be less than 20 * Length, so for 65nm that would be 20 * .065 (minimum length) = 1.3 um.
Others have told me to keep the individual finger width to less than 10 um in size - is there a rule of thumb ?
This is for matching (inter-digitization and common centroid) layouts.
Thank you.
