I simply want to check if this circuit is so prone to oscillation as it looks in simulation program. But in real live I wasn't able to to force this circuit to oscillation. All I get was damp oscillations.At first, the circuit under discussion is NOT intended to use as an oscillator - because sometimes it oscillates and sometimes not.
Both of your loop gain simulations are a good example - and you see that the condition of oscillation depends on the used RC time constant, in conjunction with the open-loop characteristic of the opamp.
Thus, no surprise that it "fails" sometime. I suppose for lowering the RC time constant the circuit will (perhaps) oscillate.
