Abstract
A resistor formed in the same epitaxial layer of semiconductor material in which a Hall element is formed is used to provide a temperature dependent voltage source which is inversely proportional to the resistance of a temperature sensitive load resistor on the Hall element output. A current mirror circuit is used to apply a current proportional to the current through the epitaxial layer resistor to the load resistor so that the voltage across through the load resistor varies in a direct relationship with the sensitivity of the Hall element.
