Hello,
I am designing a low-pass filter using a op-amp and has a cut-off frequency at 1.5 KHz. I can't assume it is ideal and when looking at the manufacturers datasheet they provided a bode-plot of the open-loop gain frequency response.
I am wondering how I can use the bode-plot in the datasheet to determine the frequency response of the op-amp?
I have tried modelling it using feedback control with this equation:
T(s) = G(s) / (1 + G(s)H(s))
The problem with this is I keep getting back the same numbers as the ideal response and I am not to sure how to do the phase.
Thank you!
