Hii,
   Can I get EKV model .18um technology file anywhere?

thanks in advance

I think there is tool available with translates a BSIM to a EKV-model.
But it is not for free.....

Check the EKV official website.


Regards

Hi, is there a tool to convert PSP to BSIM or vice-versa ? Thanks..

I've never heard of one.  The models are very different (surface-potential vs threshold-voltage).

Hi,

There is no tool that can convert from one transistor model to another - at least not from the same family. Even if it did exist there would be little use for it as the accumulation of errors in fitting the one model's parameters to the results of another one's fit to measured curves would render the results with too much error. Either a foundry sticks to one model or it characterizes the models always from (the same) set of measured curves.

If you want to do this anyway, the home-made recipe is to retrieve the characterization procedures for the model you want to fit, translate these into simulations against the curves from the reference model and run a circuit optimizer to perform the fitting. For a very rainy Friday afternoon, I guess.

Cheers,
Marq
