Project Takes 2 input signals. One 0 to 5V representing desired current, the other 0 to 5V representing the MAX current. The output is linear with respect to the input signal.
I've tried using an op amp voltage to current amplifier but i cannot get it to work properly.
I plan on using a comparator to selector to choose the correct signal to drive the current source. But the current source is what is giving me problems now. Any tips out there. Please feel free to help.
