can anyone tell how to find the conductance at node in cadence ...

Surya,

This should have been posted to the circuit simulation since your
question is tool related. You also refer to the tool that you seeking
help with ADE, Spectre, ...

Have you connecting an ac current voltage source at the target
node and forced an ac current, mag=1? Note: the other sources
need to be disabled for this test.

Question for you, how would you calculate the conductance from
the response?

Best Regards

Sheldon

Hello Sheldon
Thank u for reply.
Actually in my circuit i have to find conductance at input node and output node,,and i connected Rf input source and output source at that nodes respectively.
and i done S-parameter analysis, in that from Y-parameter i found Y11 and Y22. I thought these are the conductance at input node and output node.

Can you tel me is my way of procedure is correct or not ..
Thank u
surya

Your approach based on S-parameter Analysis is appropriate if "port" never affects DC operation point of circuits.
See http://www.designers-guide.org/Forum/YaBB.pl?num=1240334878/16#16

If not, your approach is not appropriate.
