There is one problem which I am facing while running STB(stability) over corners for an op-amp in closed loop. Sometimes my Phase plot starts from 180 deg and sometimes it starts from 0 deg. I have no clue why is that happening ?
Although I have tried trasnsients it doenst show any thing strange and system seems to be quite stable.
Thanks in advance !
Thanks Andrew for a quick reply.
I will mail my problem in customer support tab as you mentioned.
