How can I re-create this circuit in simulink so that it will give me the transfer function and then how can I plot the response on a bode plot on matlab. Thanks

Hi @Aaron Frost

If you have Simscape, then you should be able to create the model of the Op-Amp circuit within the Simulink environment.

If you merely want to obtain the Transfer Function and to make the Bode plot, then you should perform analytical calculations with pen and paper, which I think the approach is much faster and more rewarding because you will understand the electrical circuit principles.
