Abstract: A sensor system method of production includes forming first and second structures of the magnetoresistive system, heating the first and second structures, applying a magnetic field in a reference direction to the first and second structures, and cooling the first and second structures to fix a reference magnetization in the first and second structures in the reference direction. The structures are heated to near or above a blocking temperature, whereby the shape anisotropy of the first structure forces the reference magnetization to rotate into a first new orientation and the shape anisotropy of the second structure forces the reference magnetization to rotate into a second new orientation whereby the reference magnetization in the first and second structures rotate in opposite directions. The rotated reference magnetizations of the first and second structures are pinned in the respective new orientation.

Abstract: The present disclosure is directed towards a sensor interface module that delivers a supply voltage to a plurality of sensors, and which exchanges data signals between the plurality of sensors and a control unit (e.g., an ECU). The sensor interface often employs a single-bit comparator (or a coarse analog to digital converter (ADC), e.g., a 2-bit or 3-bit ADC) to track signals to be exchanged between the sensors and controller over the sensor interface. Compared to power hungry ADC with more bits (e.g., 32 bit ADC), the single-bit comparator/coarse ADC limits hardware complexity and power consumption. In addition, in some embodiments the sensor interface module can include an estimator and assist comparators to speed up the tracking ability of the sensor interface module. In this way, techniques provided herein facilitate reliable, low-power communication between a control unit (e.g., an ECU) and its corresponding sensors.

Abstract translation: 本公开针对传感器接口模块，其向多个传感器传送电源电压，并且在多个传感器与控制单元（例如，ECU）之间交换数据信号。 传感器接口通常采用单比特比较器（或粗略的模数转换器（ADC），例如2位或3位ADC）来跟踪通过传感器接口传感器和控制器之间要交换的信号。 与功耗更大的ADC（例如32位ADC）相比，单比特比较器/粗略ADC限制了硬件复杂性和功耗。 此外，在一些实施例中，传感器接口模块可以包括估计器和辅助比较器，以加速传感器接口模块的跟踪能力。 以这种方式，本文提供的技术便于控制单元（例如，ECU）与其对应的传感器之间的可靠的低功率通信。
