Abstract
A magnetic field sensor is disclosed. The magnetic field sensor includes a first magnetoresistive element and a second magnetoresistive element arranged as a half bridge. The magnetic field sensor also includes two or more conductors adjacent to the first magnetoresistive element and the second magnetoresistive element. The two or more conductors can carry a bias current and a compensation current such that the bias current and the compensation current flow in the same direction adjacent to the first magnetoresistive element while the bias current and the compensation current flow in opposite directions adjacent to the second magnetoresistive element.
