Hi Jory,
I have compared both the loop inductance and partial inductance and
cannot have the values agree.
Here is the inductance from HSPICE fieldsolver and it is per meter
+ Lo = 3.684847e-07 2.023918e-08
+ 2.023918e-08 3.684847e-07
To compare with FastHenry, I multipled the above to 25.4mm as the
length of the conductor is 25.4mm and the results are:
+ Lo = 9.3595114e-9 5.1407517e-10
+ 5.1407517e-10 9.3595114e-9
Compare to FastHenry (partial inductance) below, the results are still
very far away.
Row 0: 2.99871e-008 1.61083e-008
Row 1: 1.61083e-008 2.99868e-008
Does anyone know why?
Thanks,
Andy
