First of all, many thanks for the useful comments...
I checked the IV curves in both forward and reverse bias conditions. I can see the difference between two photodiodes only above approx. 0.4 V of forward bias. Is there any other way to see this difference; for instance can a CV measurement...
Hi,
First of all, thanks for all your comments. I should explain the problem in more detail. First of all, I do not have any datasheet as it is a home made photodiode. My problems is that the response of one is a bit different than the other in terms of impedance match. Otherwise they seem to...
Hi E Kafeman,
Thanks for the info but I am rahter interested in measuring the series resistance. The operation of a photodiode is no problem, I am trying to determine this resistance an preferably at voltages of typical diode operation, namely at reverse bias. Any idea?
Thanks

Hi IanP,
I should measure the series resistance of the photodiode. Is there any common inductrial practice to determine the series resistance? I would appreciate any information on this matter.
Thanks and regards

Hi,
I would like to measure the series resistance of a photodiode. Could you please help me on this matter. I bias the photodiode in the forward direction (0.3-0.5 V) and try to analyse the data but I am skeptical about this method as we do not know whether such high currents flowing may damage...
