Can anyone suggest a simple voltage to current converter?

I need to get out a 4-20mA output for a 500mV-2.5V rectified and filtered input voltage.

Essentially that's a 0 to 20mA output for 0 to 2.5V input.

There's nothing special about that, look for any simple voltage to current circuit and use appropriate values.
