Hi all. I can't find any information on device matching in the pdk docs. Specifically I am looking for Avt numbers. If this is not included in the docs it is a big gap in my opinion as any design with offset / matching requirements must then be designed quite blindly in the absence of hand calculations. They are amongst the first numbers I always look for in a new pdk. If they are not there I would be more than happy to compile them for NMOS / PMOS devices and submit for documentation.

Seems this info is not available. Not to worry, Ive a nice octave script which will output the numbers. Im away for next week so when I come back will put together the numbers for the FET's and then at a later date, for the R's and C's. Stay tuned!
As promised, please find attached the matching co-efficients for the 1v8 PMOS / NMOS devices in the PDK. As shown in the ppt, next I will be characterising the poly resistor / momcap matching coefficients. These numbers are an absolute must for anyone looking to create a chip with high yield. If anyone has inputs on this please share.
