摘要： The invention relates to a magnetic sensor device comprising excitation wires (11, 13) for generating a magnetic excitation field and a magnetic sensor element, particularly a GMR sensor (12), for sensing magnetic fields generated by labeling particles in reaction to the excitation field. The magnetic excitation fields are generated with non-sinusoidal forms, particularly as square-waves, such that their spectral range comprises a plurality of frequency components. Magnetic particles with different magnetic response characteristics can then be differentiated according to their reactions to the different frequency components of the excitation fields. The magnetic excitation field and the sensing current driving the GMR sensor (12) are preferably generated with the help of ring modulators (22, 24). Moreover, ring modulators (27, 29) may be used for the demodulation of the sensor signal.

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 magnetic sensor device is suggested. The magnetic sensor device comprises at least one magnetic field generator, a magnetic sensor element (8), means (17) for supplying a frequency modulated sense current to the magnetic sensor element (8). A rejection means (18) is arranged in the signal path between the magnetic sensor element (8) and an amplifier (11). The rejection means (18) is apt for rejecting a signal component at the modulation frequency. The rejection means (18) allows reducing the required dynamic range of the amplifier (11) significantly because a large part of the sensed signal carrying no measurement information is not transmitted to the amplifier (11).
