Title: How to derive a symmetric inductor model by Asitic
Post by JC on Dec 1^st, 2007, 2:54pm

I want to derive a lumped model for a symmetric inductor (center tapped inductor) by using Asitic so that I can use the model in Cadence in this way:

| k |
Ind1 <-------------> Ind2
| |
--------------------------
|
------
---

where k is coupling factor, Ind1 and Ind2 are the lump model in the format as follow

------ ind -- Rs --------
| |
Csub1 Csub2
| |
Rsub1 Rsub2
| |
sub sub

Ind1 and Ind2 are the half parts of my center tapped inductor.

Please give me some suggestion. Thx.
