    摘要: The present invention provides a magnetic sensor device comprising a plurality of magnetic sensor elements having a sensitive direction. At least one of the magnetic sensor elements (43) is provided with a flux-guide (44) for concentrating onto the sensor element in its sensitive direction a magnetic field applied to the magnetic sensor device. The applied magnetic field is thus bent into the sensitive direction of the magnetic sensor element by the flux-guide. In that way, the field strength and/or orientation of the applied magnetic field can be measured in the absence of magnetic particles. This may be used for, for example, calibration of magnetic sensor devices.

    摘要: The invention relates to a magnetic sensor device comprising an excitation wire for the generation of an alternating magnetic excitation field (Bi) and a GMR sensor (12) for sensing reaction fields (B2) generated by magnetized particles (2) in reaction to the excitation fields. Moreover, it comprises a compensator (15) for the generation of a magnetic compensation field (B3) that adaptively cancels predetermined spectral components of all magnetic fields (B2, B3) which lie in the sensitive direction of the magnetic sensor element (12). Measurements of the GMR sensor (12) are thus made robust against gain variations of the sensor.

    摘要: A preprocessing unit converts an analog signal to a processed signal at a sample rate controlled by a first clock signal. A digital phase locked loop locks on the processed signal and outputs a phase signal using the first clock signal. A bit decision unit outputs a digital signal and a third clock signal using the phase signal, the first clock signal and an output signal from the preprocessing unit. A clock divider produces the first clock signal from the second clock signal. A quantizer produces the output signal by quantizing the analog signal amplitude. A phase detector determines a phase difference between the output signal and the second clock signal to feed an amplitude that indicates a phase difference. A sample and hold unit samples the output signal using the second clock signal and holds samples of the output signal for a clock period of first clock signal.
