ABSTRACT:
A position sensor is provided with the capability of detecting a quadrature signal by the provision of first and second magnetically sensitive devices. The first magnetically sensitive device comprises a Hall effect element or some other device which is capable of sensing strength of a component of a magnetic field which is perpendicular to a preselected plane. A second magnetically sensitive device is provided which is capable of sensing the component of a magnetic field lying in the same plane. In a preferred embodiment, the first magnetically sensitive device is a Hall effect element and the second magnetically sensitive device comprises at least one magnetoresistor. The first and second magnetically sensitive devices are disposed on a common substrate and arranged to have a common geometric center. When the device is associated with a moving target that comprises a plurality of magnetized regions, accurate determination is possible with respect to both the rate of movement and the direction of movement of the target.
