My question is about how much Vbe for a bipolar at a given current do you see vary from typical corner to slow corner and from typical to fast corner in the process models. I have normally seen +/- 2.5% normally.
I recently see in 1 process that the corner variation setup is 0.3% or 0.6% which seems really good. What they have done is set the corner limits as the 4 sigma limits of the parametric test data they have received from previous lots.
