Hi guys,
I have Hamamatsu S9648-100 photodiode.
The photodiode must be reverse-biased so that a positive potential is applied to the cathode.
To eliminate the hgh-frequency components, it is recommend to place a load capacitance CL in parallel with load resistance RL as a low-pass filter.
Cut-off frequency fc=1/(2*pi*CL*RL)
my question is how do we get the CL and RL?
attached below is my circuit!
