Abstract
The reference circuit includes a current mirror for providing first and second current paths for the conduction of respective first and second currents. The current mirror imposes a current level relationship between the first and second currents. A load, preferably resistive, is provided in the first current path for predominantly establishing a predetermined level of the first current. A transistor having a temperature coefficient of a predetermined polarity and a resistor having a temperature coefficient of a complimentary polarity are provided in the second current path for providing temperature compensation. Finally, a load compensation stage is provided in the first and second current paths to provide a thermal compensation feedback path from the transistor and resistor compensation elements to permit stabilization of the first current level with respect to temperature.
