Hi,
I need some guidance or basic starting point on this. I need to
generate a current that is the difference of two currents. One of the
currents is constant at ~ 25mA and the other (input current) can vary
from 0 to 1000mA. My original idea is to do a I-V conversion on the
two inputs, do a voltage subtraction of the two using a basic opamp
difference circuit and then an V-I circuit to convert back to
current...but there has to be a cleaner way.
