If I have 3 photodiodes, PD1, PD2, and PD3. All of the cathodes are connected. I am placing a picoammeter in series with PD2 to measure the generated photocurrent but I am leaving the anodes of PD1 and PD3 unconnected. I don't believe that PD1 and PD3 would contribute any current, but can someone else verify this for me please?
Thanks.
Picoamp meter...wow..That's tiny... I wonder if the unconnected anodes on the 2 photodiodes will act like antenna's and your picoamp meter will flicker with the strongest AM radio station?? D from BC
I haven't noticed that kind of affects. I am more concerned with things like the open circuit voltage of PD1 or PD3 or their current contributions.
This is just a DC point of view... Imagine the photodiodes are 100V batteries that are disconnected at one end.. Do you think that will do something..? It shouldn't..There's no circuit. (Neglecting Rair..) D from BC
Thanks, that is basically what I was thinking, but its nice to have someone else verify it.
what is the other side of the picoammeter connected to? The anode of PD2?
