The following image depicts the transfer function of an compensated against an uncompensated OpAmp.
If the internal Miller-compensation capacitor results in an additional pole at low frequency I would expect it to yield an ADDITIONAL phase shift to the existing phase shift of the uncompensated circuit. So why is the resulting phase shift smaller as compared to the uncompensated circuit for f>20kHz?
This seems to be true, because a simulation with LT Spice gives the same result. Obviously, the system transfer function is not a simple linear cascading of low-pass elements, because in this case I would get additional phase change. Can it be understood qualitatively why the compensation "masks out" the intrinsic frequency response?
