Hi Henry:
You might just try using a spreadsheet to calculate the complex impedance of your model circuit and manually play with
the parameter values and get them to match the measured data.
Have Fun,

Hi time-nuts!
If I remember correctly here was a discussion about an older HP impedance measurement equipment. The one which is able
to calculate a 6 ideal parts replacement circuit for the measured passive device.
How does is it works? I would like to fit parts for simulation in SPICE. So I need something like a algorithm to fit
for minimum error a input table with complex numbers (frequency-sweep) to this 6 part circuit. For example the
universal capacitor component in LTspice is able to hold RLC and even XTAL data and more like residual current for
electrolytics.
Any ideas?
Thanks -
Henry
