Voltage-to-current converters

Posted on Apr 6, 2012

A simple voltage-to-current converter is shown in the figure. The current out is 0t or Vjn/R. For negative currents, a pnp can be used and, for better accuracy, a Darlington pah-can be substituted for the transistor. With careful design, this circuit can be used to control currents of many amps.
