In dependence of EM(S12), there is a rejection, does anybody know why there is a rejection? This is not repeated by dependence of the extracted equivalent model.
1、I used the ground plane(10 µm substratemml) under the inductor instead of the BCB layer in my reference paper, what's more, if I remove the ground plane,I can not map metal layer between the 300 µm substrate and the bottom cover, then I can not define the layer42 intruded into substrate...
I have simulated a transformer proposed in the following paper, but I got very low L, Q and efficiency.
Can you tell me what's wrong with my workspace, mml_wrk.zip, in ADS2011?
my substrate
my transformer
Cu_mml resistivity of 3.9 μΩ-cm
conductivity
simulation results
obiviously, it's wrong,
the resistance is too big! Do I set the wrong conductivity?
the primary coil is a capacitor! why?
I know how to get the layout of a tranditional front-side on-chip transformer in momentum. But, I don't know how to get the layout of a Silicon-Embedded transformer in momentum, because the fabrication of the transformer is based on some special process including trench formation, thermal...
I have checked my project.
there is a gap!
thank FvM and volker@muehlhaus.

I think I have solved my problem:
substrate file:
modified substrate file
simulation results of the primary coil:
can you tell me I am right or not? can you tell me some better way to solve...

can you tell me how to add the ground reference? can you check my project? I have attached the momentum project here, including the GDSfile, streammap file and the substrate file.
Help me!

how to analyze the S parameter when you simulate a transformer in momentum?
can you tell me the S parameter right or wrong?

I think the impedance from S11 means Z11. Why the real part of Z11 is so large(2.000E9) when frequenz zero? Why the imaginary part of Z11 is...
