spectre transistor output resistance
How can I get output resistance of a transistor (ro) by spectre simulator in Cadence software.
I can only get the parameter ron from DC operating point. It is rds=Vds/Id, not ro=σVds/σId.
And I can get the λ from model parameter. Is it named pclm? But result of the formula ro=1/(λId) is not correct too.
Who can help me to get the small-signal output resistance?
Thanks!!
