Steve,
I am trying to extract from the R,X,Z plot from the vendor.
As per your suggested in your doc. "CPAR can be obtained by solving for the
parallel Admittance at a frequency well beyond the impedance peak". I
calculated the values(From the enclosed graph) and the calculation as attached.
But I found that there is a mismatch between the calculated value from LTSPICE
in Max. Impedance@100MHz from the vendor specified. Please suggest the method
to calculate.
Thanks
Jack

Jack, you can extract the effective parallel capacitance either from S
parameters or an R, X, Z plot.
