Hi guys, I was looking at how to do the stability analysis. I saw in some schematic that now I am not able to find anymore, do the stability analysis with a big L and C. Someone has this test example? I didn't find literature around this case.

I guess this is the kind of testbench you are asking for.

Yes! Exactly! I would like to analyse the theory about this system to do the stability analysis. Is available the test bench?

This is the test bench i have posted above.

thank you very much! here there is also the other method. I tried this method but is not clear what kind of surces i need to you. https://education.ingenazure.com/ac-stability-analysis-ngspice/ Vprobe2, is a DC source, Iprobe is an Idc current source, and Vprobe1, is not clear. I didn't found the same simbol in xschem. Any suggestion? did you tried this method?
