In the above image, I've drawn out a prototype (?) schematic for a photodiode amplifier. This is a departure from what would normally be used since I am intending on using only discrete transistors as the amplifying devices for this preamplifier stage. I would like to know how to calculate V_out/I_in given the values of R1 through R6. R1 and R3 could be changed as well.
I previously posted this in the "projects" section of this site but I believe it belongs here instead.
