Hi,
Thanks for the feedback!
I actually didn't develop a spec for the system, the aim is to design a sensor that can detect the colour of any physical object and replicate the colour using RGB LEDs as accurately as possible (yeah think about it now it is indeed very vague...)
I initially...
Hi,
Thanks for the fast response!!
Yes indeed, didn't notice that the input current has to be in uA range...
I found a low bias current op-amp but forgot about the mux..
This stupid error cost me 20% for my design report :'(
Anyway, since I only need my system bandwidth to be 20Hz, the...
Hi all,
The circuit is designed as a colour sensor, using a 3-channel output photodiode to detect the RGB light intensity.
In order to save component costs and in an attempt to produce a more compact solution, I included a 4-1 multiplexer to switch between the 3-channels of the photodiode...
