ACTIVE SENSOR CIRCUITRY

Abstract:

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 storage element 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.
