Stability analysis of circuits with active devices  in Eldo

Discussion created by on Apr 6, 2018

In  Eldo-RF manual, I found "local stability analysis" using .SSt STABIL for a oscillating circuit based on npn transistors along with R L and C.

But I am trying to use it for my circuit that is made up of OTA and R, C. Is it possible using that command as I am failing to do with this?

Is it only for passive components?

My question is " How can I make the pole-zero plot or root locus plot of a linear system or a trajectoy for a oscillating system, where the system is OTA-C and I am simulating its SPICE code through Eldo?
