Claim 0:
1. An apparatus for providing a bias current to a hall sensor, comprising:
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 to the hall sensor based on the bias current control value,
wherein the bias provider comprises:
a first bias provider configured to produce a variable first bias current based on the bias current control value; and
a second bias provider configured to produce a second bias current less relevant to the bias current control value than the first bias current, and
wherein the first and second bias currents are provided in the hall sensor together.
