Abstract
An apparatus for providing a bias current to a hall sensor includes: a bias provider configured to provide the bias current to the hall sensor; and a processor configured to produce a bias current control value based on a node voltage between the hall sensor and the bias provider, wherein the bias provider is configured to vary the bias current based on the bias current control value.
