  • Magnetoresistance-effect magnetic sensor of the temperature compensating type
    Patent number: 5589768
    Abstract: A magnetoresistance-effect magnetic sensor provides an effective output even in atmospheres higher in temperature than those relevant to prior art sensors. The invented sensor has magnetoresistance-effect devices each connected to a constant current circuit. The voltage across each device is output as a magnetic sensitive output. With this structure, a temperature rise induced decrease in magnetoresistivity of the device is compensated for by an increase in intrinsic resistance thereof attributable to temperature rise. Thus, the sensor provides a reliable output even in high temperature atmospheres.
