Hi Raja,
Okk! Hmm! I guess a lot of phase plots do a bit of fall and then boosted up by a zero. So in all those cases one has to check for encirclements...

Meanwhile PZ analysis is running out of memory and giving no zero, no poles as output

I am doing this thru cadence ADE environment. I have selected the output nodes (pos and neg), input voltage source. Now do I need to sweep frequency?
Thanks,
Rajdeep
