Thanks for your reply.
It is a 0.18 um technology, and I am working for college and I guess I won't worry too much about the error.
It is a bulk technology, and I don't know the best way to attack the leakage at high T.
Yes, I did a lot of high T measurement (DC +AC) on transistors, and I need high T model badly. It will be of great help if you give me a hint how to develope high T device models. I know only the basic skill to extract room temperature dev model.
thanks
