Hi:
I am currently working on an application – that includes a photodiode and a TIA. I have a requirement from the resolution of this device, that the signal should minimum be 30db – and I don’t have much power to do good with.
So my question is – what kind of noises should I consider from the photodiode (beside shotnoise, themal noise & internal noise (TIA)).
Also, how can I choose my photodiode and emitter, so I can collect as much light as possible (angles, size etc), while still have a small noisefloor.
Thank you in advance.
