Photodiode equivalent for noise calculation

[furiaceka]

Hi,
I have a photodiode equivalent like this:

Can I transform this equivalent in a series between a voltage source (Vg) and a resistance (Rg).
Because this photodiode is the input of the negative pin of an opamp that work like an integrator to amplify photodiode's signal and I need to calculate the total power of thermal noise introduced by the opamp.
To do that I need the value of resistence of source that is different from zero.

The model doesn't´reflect diode shot noise.

You might want to look at some of the application notes from TI if you want to analyse the noise of transimpedance amplifiers eg https://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=SBOA060&fileType=pdf
