Abstract
A current reference with reduced sensitivity to process variations includes two current sources. The first current source has an output current that is sensitive to process variations. The second current source has, as a component of its input current, the output current of the first current source. The input current to the second current source is substantially constant because the process dependent component has been removed by the output current of the first current source. Variable resistors internal to the current source are set using a control loop circuit and an external resistor.
