Re: [moved] Which MOS model I have to choose for a 5GHz LNA in ADS ?
If you're talking compact model, I doubt any will fully satisfy. The
lack of close-in inductance features matters at these frequenciese ,
distributed gate resistance as well. I have seen the modeling dudes
stick with subcircuit approaches for these reasons (and maybe
others, but what I see in the subcircuits is added Ls and Rs with
elaborate L, W, m dependence math.
Your best bet is probably the foundry models if you are at an
RF-interested (to the point of applying actual effort) foundry.
If you're looking for cheap and a digital foundry flow, you are
pretty much on your own.
You should always look to the foundry first (if this is only an
exercise, pick one who looks to have succeeded, still, and try
to get access to the PDK for a capable flow).
