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.
