A simple voltage-to-current converter is shown in the figure. The current out is IOUT or VIN/R. For negative currents, a pnp can be used and, for better accuracy, a Darlington pair can be substituted for the transistor. With careful design, this circuit can be used to control currents of many amps. Unity gain compen-sation is necessary.
