For my project, I would like to amplify the output from a photodetector for subsequent analysis with an oscilloscope.
The output of the photodetector is a current. Since we are using a voltage-amplifier, we would like to "convert" this output to a voltage by having a resistor after the photodetector but before the amplifier. Would you recommend using a resistor in series (e.g. a 50 Ohm series resistor) or would you rather use a t-piece with e.g. a 50 Ohm termination?
It would be really interesting to know the difference between those two options.
Thanks a lot for your help!! :)
