I am simulating an op amp circuit for its stability, the bode plot has a -6dB slope per decade .
I have attached the both the circuit and the result, can someone please share where I was wrong and what changes could be made.

Why do you think the simulation is wrong? Looks like correct loop gain simulation setup.

In case you want to measure closed loop gain, the voltage source would be placed at the amplifier input.

You are measuring octave rather than decode gain slope.

The slope should ideally be -20dB per decade and since the setup is an ideal one should it not be -20dB

For decade slope as well the readings are same
