Abstract
A Hall effect device includes a Hall element and a voltage regulator. The Hall element has first and second bias terminals, or nodes. The Hall effect device maintains, or regulates, a voltage at a point within the Hall element between the first and second bias terminals at about a constant voltage level, while generating a Hall effect voltage. In particular embodiments, the Hall effect voltage is, thus, prevented from substantially varying with the temperature of the Hall element.
