hi
how can i calculate the Ri, Li, Gi, Ci parameters for a frequency dependent
unit-cell Debye RLGC model for a power/gnd plane pair? 1st order or up to 3rd
order Debye model would be good.
are there any equations?
(Debye models introduce additional RL and GC elements into the 4 element
original RLGC model to reflect the frequency-dependency, and with staying with
basic circuit elements, suitable for spice)
i would like to make frequency dependednt spice 3f5 models (not w-element
model, since its not compatible with most of the spices) from arbitrary power
planes, with lumped-element grid.
I found application notes where in the examples they just shown the calculated
values, without describing the calculation.
regards,
Istvan Nagy
