摘要： The invention provides a magnetic field sensor or current sensor which can exhibit a substantially linear relationship between the sensor signal and the logarithm of the magnetic field or current. The sensor may be used as a wide dynamic range sensor which can offer a constant relative sensitivity and a uniform SNR over several decades. The design of the sensor device may be implemented in discrete magnetic field sensors or current sensors as well as in integrated current sensors in ICs comprising MRAM modules.

摘要： Devices (1) comprising sensor arrangements (10) with field detectors (12) for detecting components (18) of magnetic fields in planes of the field detectors (12) and with movable objects (13) for, in response to tilting movements, changing at least parts of the components (18) of the magnetic fields in the plane; of the field detectors (12) are made less sensitive to in-plane stray fields by providing the fold detectors (12) with saturated field-dependent elements (31). The movable object (13) 1 nay comprise a movable field generator for generating the magnetic field, or the movable of object (13) and the field generator (11) may be different objects. The magnetic field is such that the field-dependent element (31) is saturated. The field generator (11) is smaller than the field detector (12), and the movable object (13) is larger than the field detector (12), to reduce alignment problems. The movable object (13) has a pivoting point close to the field detector (12).

摘要： A magnetic sensor has a magnet (30) and a magneto-resistive element (20), arranged on a substrate such that magnetic field lines through the magneto-resistive element are substantially parallel to a plane of the substrate. Movement of a movable magnetically permeable element (40) near the substrate is detected as it alters the number of field lines through the element. It can be more sensitive than devices arranged with perpendicular field lines, and can be easier to manufacture and integrate. Applications include analog pointers, pressure sensors and microphones. It can use magnets placed either side of the element to detect changes in size of a gap above the element. As the gap closes, less of the parallel oriented field passes through the magneto resistive element.
