Patent number: 9638548Abstract: Embodiments relate to predictive output switching threshold determination systems and methods for sensors, for example magnetic field sensors. In embodiments, at least one individual switching threshold is determined predictively, rather than reactively, for each tooth or pole of a ferromagnetic tooth or pole wheel, respectively. For example, in one embodiment, the number of teeth or poles is programmed, and an optimal threshold for each tooth or pole is determined during a rotation of the wheel. The determined optimal threshold for each tooth is then used for that tooth in at least one subsequent rotation of the wheel, with calibration optionally taking place in future subsequent rotations. Thus, in embodiments, thresholds are predictive for each individual tooth or pole rather than reactive to an adjacent tooth or pole.Type: GrantFiled: June 25, 2012Date of Patent: May 2, 2017Assignee: Infineon Technologies AGInventors: Razvan-Catalin Mialtu, Dan-Ioan-Dumitru Stoica, Heinz Untersteiner, Catalina-Petruta Juglan

Patent number: 9575143Abstract: The present invention discloses a design for a single-chip dual-axis magnetic field sensor, based on magnetic tunnel junction (MTJ) elements and permanent magnets integrated on a semiconductor substrate to produce two types of sensor bridges that detect orthogonal magnetic field components. The orthogonal magnetic field component detection capability results from the different types of sensor bridges that can be produced by varying the shape of the MTJ elements and the bias fields that can be created by permanent magnets. Because the permanent magnets can create orthogonal bias fields on the different sensor bridges, it is possible to use a single pinned layer to set direction for both sensor bridges. This is advantageous because it permits the two-axis sensor to be fabricated on a single semiconductor chip without the need for specialized processing technology such as local heating, or deposition of multiple magnetoresistive films with different pinned layers setting directions.Type: GrantFiled: May 23, 2012Date of Patent: February 21, 2017Assignee: MultiDimension Technology Co., Ltd.Inventors: James Geza Deak, Insik Jin, Weifeng Shen, Xiaofeng Lei, Songsheng Xue
