You haven't said what voltage range you're after.
Is this college work? A resistor will do that. A 1  hm: resistor will convert voltages between 0-1V to currents between 0-1ľA. The output impedance will also be very high - 1Mhm:.A 10M hm: resistor will convert voltages from 0 to 10V to 0 to 1ľA.Just use Ohm's law.
