Which Spice model
I'm confused !
So far for my self study of analogue design I have used the spice data of a MOSFET as found in Allen/Holberg ie 1um gate..
I have been trying to tie up the theory of ring oscillators to ADS simulations and came across a worked example using the CN20 process.
Looking on the web I found several spice models for this process one being BSIM2 and the other BSIM4, but they give completely different results when running transient/HB simulations - why should this be ?
Is there 'popular' spice model that is commonly used throughout industry that I could adopt ? and which spice model should I go for ?
ie which BSIM and level and from which fab process ?
cheers
