A current reference, which may be fabricated independently, on a die, as part of an integrated circuit, or a system, or in various other forms, is disclosed. The current reference may include a voltage source having a substantially temperature stable output voltage, a first semiconductor device biased by the substantially temperature stable output voltage to provide a first output current, and a second semiconductor device providing a second output current, wherein a reference current is provided approximately equal to the difference between the first and second output currents.
