hello all,
currently I'm working on level 72 mosfet in hspice.as the temperature changes the leakage current should be change.but when i simulate it in hspice there is no effect on hspice.so anyone can help me out ???
 

Leakage current and mobility in hspice

can anyone help me out from how to do a code for leakage current and mobility in hspice.???

Suggest you show your model file(s) and how you invoke the MOSFET(s).
 


Re: Leakage current and mobility in hspice

Leakage and surface mobility are both affected by the
NSS (number of surface states) or NFS (number of free
states) parameters, at lease in the older LEVEL= models.
Subthreshold slope as well (which may or may not be
the dominant factor in Vgs=0 leakage, depending on VT
and slope).
 
I'm using 10nm ptm-MG file from http://ptm.asu.edu this site.my aim is a effect of temeperature on parameters of mosfet.when i am simulating this file at different temperature.there should be a change in parameters value as temperature changes.but there is no change in parameters value.

Since this purports to be a "predictive" model (not based
on data?) you can't presume that temperature effects
are represented well (or for that matter, at all).

Checking that would entail reading the model manual (if
any). Since this is also a new(-ish) model, evidently based
on BSIM but -not- BSIM, you should do the reading and
find for yourself what params go to what behaviors. The
models seem to be somewhat self-documenting, in that
they segregate params into functional groupings with at
least that level of commentary. But somewhere behind
this ought to be a work-in-progress modeling document.

Be sure also that whatever temperature you -think- you
are varying, is the one that has effect. Especially in self
heating aware models (such as these) the temperature
variable may not be the primary SPICE built-in global one.
