Title: Cadence Spiral Inductor Modeler
Post by saumi9de on Mar 29^th, 2004, 11:44am

Hi all,

I am working on TSMC 0.25u RF process for my project.
I am having some problem modeling the inductors for this
process in Cadence Spiral Inductor modeler. I had created
a model file using the information provided in the PDK.
However, upon comparing the models generated by the Cadence
modeler with the subcircuit for the charaterized inductors provided
with PDK a large variation is observed, especially in the
capacitanes across the series inductors, and the resistance
to ground (reference).

Has anyone here modeled inductors for TSMC0.25RF or any other
process? Did you face such a problem, and if yes, could you please
suggest a workaround. Also, what usually are the observed
tolerances between the modeled and the fabricated inductors?

Thanks and best regards,
Saumitra
