One method i know is from the CV measurement .But that is not very accurate.Please help...Its very urgent. Thanks in advance.

I did that with an SOI cap (poly over nWell) and got the attached. You could do an AC analysis and step the DC vale but that won't give a direct plot of capacitance. Keith.
