摘要： A magnetic-sensing apparatus and methods of making and using thereof are disclosed. The sensing apparatus may have one or more magneto-resistive-sensing elements, one or more reorientation elements for adjusting the magneto-resistive-sensing elements, and semiconductor circuitry having driver circuitry for controlling the reorientation elements. The magneto-resistive-sensing elements, reorientation elements and/or semiconductor circuitry may be disposed in single package and/or monolithically formed on a single chip. Alternatively, some of the semiconductor circuitry may be monolithically formed on a first chip with the magneto-resistive-sensing elements, while a second portion of the semiconductor circuitry may be formed on a second chip. The first and second chips may be placed in close proximity and electrically connected together. Alternatively the chips may have no intentional electrical interaction. Exemplary semiconductor devices that might be implemented include, without limitation, capacitors, inductors, operational amplifiers, set/reset circuitry for the MR sensors, accelerometers, pressure sensors, position-sensing circuitry, compassing circuitry, etc.

摘要： A magnetic-sensing apparatus and method of making and using thereof is provided. The sensing apparatus may be fabricated from semiconductor circuitry and a magneto-resistive sensor. A dielectric may be disposed between the semiconductor circuitry and the magneto-resistive sensor. In one embodiment, the semiconductor circuitry and magneto-resistive sensor are formed into a single package or, alternatively, monolithically formed into a single chip. In another embodiment, some of the semiconductor circuitry may be monolithically formed on a first chip with the magneto-resistive sensor, while other portions of the semiconductor circuitry may be formed on a second chip. As such, the first and second chips may be placed in close proximity and electrically connected together or alternatively have no intentional electrical interaction. Exemplary semiconductor devices that might be implemented include, without limitation, capacitors, inductors, operational amplifiers, set/reset circuitry for the MR sensors, accelerometers, pressure sensors, position sensing circuitry, compassing circuitry, etc.

摘要： A magnetic field sensing device can be realized by using a magnetic sensor in electronic compassing as well as switching. A magnet can be brought in close proximity to the magnetic sensor within an electronic compass to generate a signal that a portable information device has been closed. This signal can be input to a processor or other circuitry to initiate a response to the portable information device being closed. When the magnet is moved out of close proximity to the magnetic sensor, the magnetic sensor can be used in the electronic compass. Thus, a magnetic sensor can serve two functions, namely compassing and switching, reducing the need for separate sensors to perform both functions.
