    1. I have to design transimpedence amplifier(TIA) for monitoring photodiode in Fiber Coupled Diode Lasers.
    2. I have checked for internet on how to design a TIA.
    3. I have attached a circuit diagram with formula mentioned.
    4. I have two different design approaches for selcting feedback capacitor(as in circuit attached) , one at 65 & other at 45 phase margin. Which one is most suited?
    5. Then I fed the signal to 24 bit differential adc.
    6. Any other comment or suggestions on it
