In accordance with an embodiment, a reference voltage generator includes a first current generator and a second current generator. The first current generator is configured to produce a first current proportional to a current through a first diode connected in series with the first resistance coupled between a first voltage and a second voltage, such that the first current is produced according to a first proportionality constant. The second current generator is configured to produce a second current proportional to a current through a second diode connected in series with the second resistance coupled between the first voltage and the second voltage, such that the second current is produced according to a second proportionality constant. The reference voltage generator further includes a reference resistor coupled to the first and second current generators and to and output of the reference voltage generator.
