I am trying to simulate in LTSPICE a circuit containing two op amps cascaded in series (so that individual gains will be multiplied) but for some reason the gain of the first stage is higher than the last stage, but when I remove the power pins of the last stage, the circuit behaves normally. What is happening?
I am trying to do a frequency sweep and have tried two different op amps (TL072, NE5532) but they both behave abnormally. I don't know what i am doing wrong.
I got my op amp spice models from TI.
