Hi everyone!
This is my first post, I've been working in Photodiode transimpidance circuit as a color sensor, my problem is that the output is not DC as I expected, but is sinusoidal(120Hz) function I think this is noise but I do not know what is the source or how to mitigate it.
Any suggestion would be really appreciated!
