  • Magnetic sensor device
    Patent number: 6566872
    Abstract: A magnetic sensor device has a magnetic sensor having a magnetic material whose threshold frequency is changed by a magnetic field to be detected, and the device has the so-called electromagnetically-coupled current path which is affected by the magnetic material in order to electrically detect the threshold frequency of the magnetic material. The current path is connected to an oscillator circuit, which is set so that its oscillation frequency is changed by a change in the threshold frequency of the magnetic sensor. In the magnetic sensor device, the magnetic field to be detected causes a change in the oscillation frequency of the oscillator circuit, and the change in the frequency is extracted as a magnetic field detection signal.
