  • Electronic circuit and method for resetting a magnetoresistance element
    Patent number: 8063634
    Abstract: An electronic circuit includes a primary magnetoresistance element for providing a first output signal proportional to a magnetic field. The primary magnetoresistance element has a primary maximum response axis. The primary magnetoresistance element also has a hysteresis characteristic. The electronic circuit also includes a reset conductor disposed proximate to the magnetoresistance element. The electronic circuit also includes a secondary magnetic field sensing element for providing a second output signal proportional to a magnetic field. The secondary magnetic field sensing element has a secondary maximum response axis, which, in some embodiments, is substantially perpendicular to the primary maximum response axis. In operation, the primary magnetoresistance is reset in accordance with an excessive magnetic field sensed by the secondary magnetic field sensing element.

  • Integrated current sensor
    Patent number: 7265531
    Abstract: An integrated current sensor includes a magnetic field transducer such as a Hall effect sensor, a magnetic core, and an electrical conductor. The conductor includes features for receiving portions of the Hall effect sensor and the core and the elements are dimensioned such that little or no relative movement among the elements is possible.
