FinFET AMS Design

[Akash_Joshi]

Dear All,

I want to design AMS circuits using FinFET(Double Gate). What are the models that i can use?. Also can i get a PDK(Process Design Kit) for this purpose. What are the options?

Pl Help.

Thanks

You need to get the models from one of the foundries that offer a FinFET process. There are academic models available but not sure if they correlate to the reality. For example I've seen papers biasing two independent gates in a FinFET, which does not correspond to industry FinFETs where there is only a single gate that wraps around the fin.

Oracle has a presentation on FinFET PDKs from the major foundries. http://standards.ieee.org/events/edasymposium/9-IEEE_FinFET-Korobkov.pdf

Daniel, thank you for sharing.

Hi Khaki,

Thanks for ur reply. I have seen PTM website Predictive Technology Model (PTM). Is these models good enough if we want to design any circuit from fabrication piont of view? I doubt. What is your take on this.

Hi Daniel,

Thanks a lot. I have gone through the presentation. Thanks for the information. How much would these PDKs from foundries cost us for Academic Purpose? Any idea regarding this would be helpful.

Akash,

I don't know about University access to FinFET PDKs, because the foundries offering such leading-edge technology reserve such use only for paying, commercial customers.

There's an organization called MOSIS that does offer PDKs to Universities after you sign a Non-Disclosure Agreement (NDA) and get approval. Their PDKs are planar CMOS ranging from 0.50 micron to 0.18 micron, no where near FinFET nodes at 16 nm and below.
