There is a Libra tom model in the datasheet at w-w-w.cel.com. You just enter the parameters as shown in the datasheet.

i want implement a transitor ( ne32584c a pseudomorfic hemt )
on AWR MWO, but model in datasheet is Libra IV tom model
effectly, ive checked the non linear tom1 model implemented in AWR and they seems the same
but when i go to measure the s parameters they differ a lot from that from (...)

i am looking for @DS ne321000 nonlinear model
i only have the old ver libra model, can some one help ?
Check with and down load the parameters and fill these numbers in the @DS tom's model. then you have it.
first of all thanx linda, but this is lib

Anyone can explain why the statz model work well in simulation? why other model does not. HOw about the statz model accuracy in practice?
why other model does not - thay are working very well, tom for ex.
why do u think that thay r dosnt work ?

Depends on your foundry which you have intended.Every manufacturer/foundry chooses a proper model for their products,therefore you have compulsary to use their model approximation such as tom,Angelov,Parker,EEHEMT,etc.

are there any models out there that accurately cater for the reverse mode of a pHEMT? I've had a look at various models such as the Parker-Skellern, tom, Angelov..etc..but they don't seem to model the reverse operation of a FET. This for application in frequency multipliers.

do you have any answer yet ? I have the same problem.. I am using ASITIC and have no clue of how to make a center tapped model !

can you give me an advice how I can create a model in ASITIC for center tapped inductors ?
thanks in advance,

Also this is well explained in tom Lee's book on RFICs.
First, find the parallel Q of your L||R as Q=Rp/Xp where Rp is the resistance of the RLC parallel circuit and Xp is w*L, the reactance of the L. Then use Rs=Rp/(1+Q^2) to find the equivalent series R. Use Xs=Xp/(1+1/Q^2) to find the equivalent Xs=w*L
Hope it helps.

Upload your Sonnet & HFSS project files may be due to lot of factors apartfrom what you mentioned...
Again the results you get from sonnet are very reliable...even you can vary the mesh/cell size & you will see consistant converged in most of the tools it will provide you different results with each variation.

I work on a UWB application, where I have only 1 input port availabe, but all internal blocks work fully differential.
As I do have only ASITIC available for inductor/balun/transformer modelling, and no propper handbook exists, how to come to a appropriate model now my question:
What alternative exists to come from single to differenti

I want to model an inductor in a standard CMOS technology. Attached the cross-section of the technology for the metal layering.
Ho do I set up a layout layer in ADS which includes the overall oxid which surrounds the metal layers?
And - to perform an momentum simulation: do I have to set up a substrate or layout layer cross section?

Use the right model which is supported by foundry...
You can not use every model for general purpose.For instance Triquint supports its own model tom, WIN supports EEHEMT model, other foundry can suppport-for instance- Parker model etc.
So, each model is supported by (...)

it it should be air >copper>taconic>copper>air
In this case, you have to increase the thickness of the air layer above and below the Taconic substrate. From your 3D view, this seems to be a very thin layer of air. Use something like 50mm instead. This air thickness is needed, even if you set the top and bottom cover
