Hi John,
I have a gain of 420K in first stage and about 20 in the second stage. I use the same opamp (OPA2355) in the board. I have 15V, 4.5V, 1.8V available on the board.
I have a strict risetime requirement of 300nSec at a signal of 1MHz. I use the…
Thomas;
You seem determined to measure the background illumination current, so here is a better way of doing that. It is necessary to provide a negative photodiode bias and there is some additional noise, but this circuit is simple and could employ a…
