摘要: Disclosed is a bit-detection arrangement able to convert an analog signal (AS) having an amplitude into a digital signal (DS) representing a bit sequence from which the analog signal (AS) is derived. The bit-detection arrangement has a phase detector which detect the phase difference between a quantized analog signal and a clock signal C2. The phase difference is sampled by an AD converter. The AD converter can sample at a relatively slow rate as the phase difference is a low frequency signal. The sampled phase difference is fed to a digital PLL which outputs a phase signal PHI. The phase signal and the quantized analog signal are used to recreate the digital signal (DS). The current invention is characterized in that the bit decision unit further comprises—at least one additional sample and hold unit SH2 able to sample the output signal S1, using a clock signal CSH2 and wherein the frequency of the clock signal CSH2 is equal to the frequency of clock signal CSH1 and the phase of clock signal CSH2 is substantially different from the phase of clock signal CSH1, and an output unit for outputting samples of either the sample and hold units SH1 or SH2, wherein the samples of the sample and hold unit SH1 are outputted when the phase signal PH1 indicates that the phase difference ΔP1 is in a first region and the samples of the additional sample and hold unit SH2 are outputted when the phase signal PH1 indicates that the phase difference ΔP1 is in a second region. This has the advantage that the change of bit errors occurring in the presence of phase jitter is reduced.

摘要: A sensor device and a method for the determination of the amount of target particles at a contact surface adjacent to a sample chamber include detecting, by a detector, the target particles in the sample chamber by a sensor element, and providing at least one corresponding sensor signal. An evaluation unit determines the amount of target particles in a first zone at the contracts surface and in a second zone a distance 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, such as wavelength and/or angle of incidence, may be used to extract information about the first and second zones. In a magnetic measurement approach, different magnetic excitation fields may be used to excite magnetic target particles differently in the first and second zone.

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 incidence) 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 in the first and second zone (Z2). Moreover, the temporal course of a sensor-signal (s, s′) can be evaluated, particularly with respect to stochastic movements of the target particles (1).

摘要: A detection system (100, 150) for qualitative or quantitative detection of a magnetic field property of a modulated magnetic field is described. The modulated magnetic field may e.g. stem from an adjacent electrical current (Iadj) or magnetic particles. The detection system (100, 150) comprises at least one magneto resistive sensor element (102), a current controller (104) for providing a sensing current (Isense) flowing through the magnetic sensor element (102) and a controlling means (108). The controlling means (108) is adapted for deriving at a first frequency f1 a temperature-related parameter of the at least one magneto resistive sensor. The controlling means (108) furthermore is adapted for deriving a qualitative or quantitative characteristic of the adjacent electrical current (Iadj) or magnetic particles, taking into account the derived temperature-related parameter. This second frequency (f1) is different from the first frequency (f1}). The invention also relates to a corresponding method.

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 microsensor device like a magnetic biosensor (100). The microsensor device comprises an array of probe-sensors (10.1, 10.2, 10.3) for the measurement of a physical quantity, for example the concentration of molecules labeled with magnetic beads in a sample chamber. The array further comprises a reference-sensor (10.4) that is disposed close to the probe-sensors (10.1, 10.2, 10.3) but shielded from the physical quantity to be measured. The measuring signal of the reference-sensor (10.4) reflects the influence of environmental conditions like temperature and can therefore be used to correct the measuring signals of the probe-sensors (10.1, 10.2, 10.3). The sensors (10.1, 10.2, 10.3, 10.4) are connected via a multiplexer to the same detector unit for further processing in order to minimize variations and to reduce hardware complexity.

摘要: The invention relates to a sensing device for sensing a fluid. The sensing device comprises an inlet port (20) for receiving the fluid (100) and a measurement chamber (25) for sensing the fluid (100). The sensing device further comprises a fluid channel (30) coupling the inlet port (20) and the measurement chamber (25) for transporting the fluid (100) from the inlet port (20) to the measurement chamber (25) and a fluid stop unit (50) for stopping and controllably releasing the flow of fluid between the inlet port (20) and the measurement chamber (25). This allows stopping the fluid before reaching the measurement chamber (25) and controllably releasing the fluid for allowing the fluid to flow into the measurement chamber (25), if the sensing device is ready for analyzing the fluid.
