Hi,

Is the frequency response analysis of the op-amp valid if it is saturated ?

I have applied an input signal with fixed amplitude, and i varied the frequency and recorded the gain at each frequency. Then I realised that the input causes the amplifier to saturate, so I want to know if the cut-off frequency and the roll-off will change if the amplifier is not saturated.

Thanks,
