I have a simple bjt diff pair. I know that I can run spectre with the
SP analysis and get Z11 for the input impedance, but I was wondering
if there is a way that I can get the input impedance with the XF
analysis as I can with .TF in hspice. Any ideas?

Hi Vincent,
I'm not entirely certain what it is you're trying to do, but spectre's
"sp" analysis (S parameter) analysis is probably the analysis for the
job. Read up on this in cdsdoc/openbook.
Regards,
Andrew.

--Hi, there,
Does anyone know whether spectre offers the function of measuring
input
impedance seeing into any internal node of a specific circuit? Your
help
will be deeply appreciated.
