Hello
I am designing a circuit for a photodiode. I want this photodiode to be able to work at high speeds. To do this, I used the SFH2704 photodiode made by OSRAM company.
The problem I have now is that when I connect the photodiode directly to the oscilloscope, the fall time decreases slowly, which is not the case with the commercial photodiode called the PDA10A2 from THORLABS, which has an internal amplifier. This means that the excitation source does not have much fall time, but the SFH2704 photodiode shows that there is too much fall time. I put the pulse diagram for the two photodiodes along with the information of both photodiodes.
What circuit do you suggest to solve this problem?
