Pulling my hair out with this design. I have the following design which was done using analog devices Photodiode Circuit Wizard tool so it should work. The current source in the schemeatic is the photodiode UV-035EQ. the op amps are powered by +-5V.
This setup is for more measuring low level UV light. But as soon as I place the photodiode into darkness I get a horrible waveform with a peak/trough of about +-2V https://drive.google.com/open?id=18lMKfpOSzvvhQ3yqGymRFszVO9QUYHl7
Lookig at the photodiode it looks like its working fine I've tried multiple ones and they all seem the same.
