Integrated planar indunctor simulation

[Humungus]

Hi,

I wanna simmulate a planar inductor.
Normally planar inductors are made of several metal layers conected together by vias.
The inductance value is quite easy to estimate, but Q isn't.

I wanna know if there is any sofware (Ansoft HFSS, for instance) that accurately simulates the substrate leaks, so giving a good approximation of the inductor Q.

Thanks

MWO or Sonnet can help You. If Your device have many layers, try to use CST-MWS.

You may want to check asitics from Berkeley University. It's free but easy to use ...

use hfss is ok

In HFSS, you can obtain very accurate s_parameters.

However, it is very tough to extract the parameters you needed.
Some kind of equiv-model will be helpful, you can find them on MTT papers.

Translate s-param to Y-param and settle down every parameter one by one, then you will need some optimization tool such as Hspice to anneal the rest, inter-relating elements.

Anyway, this is only my own method. I am not very clear of that yet.
I will post it alone, maybe some one much clever will have their comments.
