ABSTRACT:
An apparatus includes a Hall effect device which generates an electrical output signal upon exposure to a magnetic field. An operating current for the Hall effect device is varied by input circuitry to maintain the output signal from the Hall effect device constant with variations in temperature of the Hall effect device while the magnetic field to which the Hall effect device is exposed remains constant. The input circuitry includes a temperature responsive element which is maintained at a temperature which varies as a function of variations in the temperature of the Hall effect device. The temperature responsive element is a silicon diode.
