Finding Gate Resistance of MOSFET in spectre-ADE.

RFStuff over 5 years ago

Dear All,

We are able to find the Cgg,Cgs, Cgd and other junction capacitance of the MOS in ADE.

Is there any way we can find the Gate Resistance of MOSFET in spectre-ADE ?

Kind Regards,

Andrew Beckett over 5 years ago

This will depend on the model used. For bsim4 I see there's

59 rgbd (Ohm) Gate bias-dependent resistance.

(see "spectre -h bsim4" and search for "Operating Point").

Dear Andrew,

Thanks a lot.

We also see "rgate" as one of the operating parameters of MOS in ADE. What is this for ?

Do we have documents for other BSIM models (like BSIM6) like BSIM4.

Kind Regards,

Take a look at https://support.cadence.com/apex/techpubDocViewerPage?path=spectremod/spectremod19.1/bsim6.html

In addition (for quick help) you can see "spectre -h bsim6" (or spectre -h bsimbulk). You can see the help topics and components which have help using "spectre -h".

The documentation is at `spectre_root`/bin/cdnshelp as well as on support.cadence.com - there's a whole manual on the device equations for each model. The manual that Frank pointed to is Spectre Circuit Simulator Components and Device Models Reference.
