Whats the ideal phase shift of an inverting amplier? Is the phase shift closer to that value at high or low frequency?

    The phase shift of an inverting amp is 180 Deg.

    For sinusoidal inputs, or for considering the input in the frequency domain, there will obviously be 180 degree phase shift any given frequency. However, this is somewhat spurious thinking because it really is just an inversion of absolute direction and nothing to do with phase, even tho there is a mathematical equivalence in the frequency domain.

    A real DC inverting amplifier will eventually deviate from ideal at high frequencies.
