Patent number: 11828827Abstract: A magnetic sensor device comprises a substrate. A first magnetic sensor, a second magnetic sensor, and one or more inductors are disposed over the substrate and are controlled by a magnetic sensor controller having a control circuit. The control circuit is adapted for controlling the first magnetic sensor to measure magnetic fields under presence of a first set of magnetic fields, and for controlling the second magnetic sensor to measure magnetic fields under presence of a second set of magnetic fields generated by the inductors. The control circuit calculates a relative sensitivity matching value that converts magnetic field values measured by the second magnetic sensor to a comparable magnetic field value measured by the first magnetic sensor or vice versa.Type: GrantFiled: November 21, 2022Date of Patent: November 28, 2023Assignee: MELEXIS TECHNOLOGIES NVInventors: Samuel Huber Lindenberger, Javier Bilbao De Mendizabal

Publication number: 20230341479Abstract: The present invention relates to a field-sensor device comprising a reference field sensor providing a reference sensor signal in response to a field, a calibrated field sensor providing a calibrated sensor signal in response to the field, a reference circuit connected to the reference field sensor and adapted to receive a reference signal, and an adjustable circuit connected to the calibrated field sensor and adapted to receive a calibrated signal. When the adjustable circuit is adjusted with the calibrated signal, said calibrated signal being different from the reference signal, the calibrated field sensor provides a calibrated sensor signal substantially equal to the reference sensor signal. The field sensor device is arranged to be exposed, when in a calibration mode, to a uniform calibration field and, when in operational mode, to an operational field being a field gradient.Type: ApplicationFiled: June 13, 2023Publication date: October 26, 2023Inventors: Gael CLOSE, Arnaud LAVILLE, Stefan RIGERT, Samuel HUBER LINDENBERGER
