Title: How to use Calibre to extract parasitical L?
Post by lsfeng on Jan 25^th, 2008, 11:44pm

hi,all
I am using smic18mmrf to design a uwb LNA (3-5G),and the Calibre Xrc can only extracted the R C,but not L.
as we all know ,the parasitical L is have much effect on rf circuit,so can anyone tell me how can I get the parasitical L form Calibre and get a more presied post-simulation?
thanks in advance!

Hi,

Recent releases of Calibre have self inductance as well as mutual inductance extraction capability. You do need an asitic like tech file so it knows process cross section. The same GUI that lets you extract C,CC and R also lets you extract L. You do need the license to extract L which is a separate from RC extractor. The setup for L extraction is tricky. I myself am trying to clarify a few things about that.

That's right, you need a separate license for Calibre xL. You also need to get a newish rule file from the foundry, and that will have the inductance statements in it. It's easiest to set up the run from the gui, Calibre Interactive.

Another question:
How to extract parasitical L with gate level, not transistor level?
