can you add a 3rd stage , to the simulation that takes the 20mv out to say to 200mv for a signal suitable for a/d use, and see what the noise factor looks like , the capacitance loading effect on the 2nd stage ??
the larger diode is mainly in active area , as some that i have looked at , this add capacitance as well , which slows down the signal it can react to the aim is to have a large surface area to ensure as much of the available light hits it , also extra optical lens help both increase the active area and increase the avaiable signal ,
i will need to improve the optics as well , as much as size can allow,
