Shot noise in regular photo diodes can be easily calculated.
Noise density is in = √(2 q Id) [A/√Hz]
with q being the elementary charge and Id the diode current. See https://en.wikipedia.org/wiki/Shot_noise
This statement makes no sense to me.The input signal is modulated (the LED) with 600 Hz square wave with a duty on 1% - this gives a frequency of 60KHz

We don't know.My 3db cutoff (bandwidth) should be at least 60 KHz (fp) Right?
First calculate Rf, since it is the gain factor. Rf = Vout / IinWhich parameters should I tweak on
In my eyes the photodiode capacitance plays not a big role when the photodiode is connected to a TIA.Cd is the output capacitance of the photodiode
