Abstract
A circuit for generating a reference voltage includes a first transistor configured to receive a reference system voltage, the first transistor configured as a current source, the first transistor configured to provide a current independent of the system voltage, a plurality of diode devices configured to receive the current provided by the first transistor, and a second transistor associated with the plurality of diode devices, the second transistor configured to compensate for process variations in the first transistor, such that the plurality of diode devices provides a reference voltage that is at least partially compensated for the process variations.
