Hi guys.
I saw a led circuit like this.
the led is pulse drived, and there is a photodiode seems to be feedback to the Led driver circuit.
but it is not the standard Voltage follower or inverting amplifier or any basic circuit that I learned in the txetbook.
so I am curious how this circuit work and how to determine the values?
PS: please ignore the value of C,R.
