ACTIVE SENSOR CIRCUITRY

Apparatuses and sensor systems are described with magnetoresistive sensor configurations. An example magnetoresistive sensor configuration includes an input feed that receives an electrical current, magnetic field detection circuitry in electrical communication with the input feed, and a feedback connection in electrical communication with the magnetic field detection circuitry and the input feed.The magnetic field detection circuitry transitions between a released state and an operated state in response to an external magnetic source. The configuration further includes an electrical storageelement in electrical communication with the input feed that maintains a minimum operating voltage and current within the magnetoresistive sensor in an instance in which the magnetic field detection circuitry is operated. 本发明题为"有源传感器电路"。用磁阻传感器配置来描述设备和传感器系统。示例性磁阻传感器配置包括：输入馈线，该输入馈线接收电流；磁场检测电路，该磁场检测电路与该输入馈线电连通；以及反馈连接，该反馈连接与该磁场检测电路和该输入馈线电连通。该磁场检测电路响应于外部磁源在释放状态和操作状态之间转换。该配置还包括电存储元件，该电存储元件与该输入馈线电连通，在其中该磁场检测电路操作的情况下，该电存储元件维持该磁阻传感
