摘要： The invention relates to a magnetic sensor device for the determination of magnetized particles (3) which comprises a magnetic field generator (1, 1') (e.g. a conductor wire) that is driven with an excitation current (I I ) of a first frequency (f 1 ), and a magnetic sensor element (2) (e.g. a GMR resistance), that is driven with a sensor current (I 2 ) of a second frequency (f 2 ) for generating measurement signals (U GMR ). A preprocessed signal (uf) is then generated from the measurement signal (U GMR ) that comprises a predetermined frequency (?f), and an evaluation unit (10) separates from this preprocessed signal a spurious component that does not depend on the presence of magnetized particles (3) in the sample chamber. The spurious component (U Q ) may particularly be caused by self-magnetization (H 2 ) of the magnetic sensor element (2) in combination with parasitic (capacitive or inductive) cross-talk. Furthermore, an unknown, variable phase-shift (f SP ) in the preprocessed signal (u f ) may be determined by varying the ratio between the spurious component and a particle-dependent target component. This variation may for example be achieved if, in an optimization stage (OS), the excitation current (I 1 ) is conducted through a bypass resistor (R, R') and/or if an additional capacitor is introduced between the magnetic field generator and the magnetic sensor element. The determined phase shift can then be used to adjust the phase of a demodulation signal (u dem ) such that the spurious component is suppressed.

摘要： The invention relates to a magnetic sensor device (100) comprising a magnetic field generator (1) driven with an excitation current of a first frequency (f 1 ) and a magnetic sensor element (e.g. a GMR sensor (2)) driven with a sensor current (I 2 ) of a second frequency (f 2 ) for measuring reaction fields (H B ) generated by magnetized particles (3). In an associated evaluation unit (10), a reference component (u Q ) of the measurement signal (u GMR ) is separated that depends on the excitation current (I 1 ) and the sensor current (I 2 ) but not on the presence of magnetized particles (3). The reference component (u Q ) may particularly be produced by a combination of the self- magnetization (H 2 ) of the magnetic sensor element (2) and cross-talk related currents. The reference component (u Q ) may be isolated based on its phase with respect to a particle-dependent component of the measurement signal (u GMR ) or based on its scaling with one of the current frequencies. Monitoring of the reference component (u Q ) reveals variations in operating conditions, for example in the sensor gain, that can be used to calibrate the measurement results.

摘要： The invention relates to a sensor device(100) and a method for the determination of the amount of target particles(1) at a contact surface(112) adjacent to a sample chamber(2). Target particles(1) in the sample chamber are detected by a sensor element(SE) and at least one corresponding sensor-signal (s, s') is provided. An evaluation unit(EU) then determines the amount of target particles(1) in a first zone(Z1) immediately at the contracts surface(112) and a second zone(Z2) a distance(z) away from the contact surface based on this sensor-signal. In an optical measurement approach, frustrated total internal reflection taking place under different operating conditions (e.g. wavelength, angle of incidenceq) may be used to extract information about the first and second zones(Z1, Z2). In a magnetic measurement approach, different magnetic excitation fields may be used to excite magnetic target particles differently inthe first and second zone(Z2). Moreover, the temporalcourse of a sensor-signal(s, s') can be evaluated, particularly with respect to stochastic movements ofthe target particles(1).
