  • Patent number: 10473731
    Abstract: A reading circuit for a magnetic-field sensor, provided with a detection structure generating an electrical detection signal as a function of an external magnetic field, has a signal-conditioning stage, which is electrically coupled to the detection structure and generates an output signal as a function of the electrical detection signal; the reading circuit is provided with a full-scale-control stage that is able to select automatically a full-scale value for the signal-conditioning stage, as a function of the value of the external magnetic field, such as to prevent saturation of the same conditioning stage.

  • Patent number: 9360533
    Abstract: A reading circuit for a magnetic-field sensor, generating an electrical detection quantity as a function of a detected magnetic field and of a detection sensitivity, is provided with an amplification stage, which is coupled to the magnetic-field sensor and generates an output signal as a function of the electrical detection quantity. In particular, the reading circuit is provided with a calibration stage, integrated with the amplification stage and configured so as to control a feedback loop in such a way as to compensate a variation of the detection sensitivity with respect to a nominal sensitivity value.

  • Patent number: 9279867
    Abstract: Described herein is a biasing circuit for a magnetic-field sensor; the magnetic-field sensor is provided with a first detection structure, which generates a first electrical detection quantity as a function of a first component of an external magnetic field, and a second detection structure, which generates a second electrical detection quantity as a function of a second component of an external magnetic field. The biasing circuit electrically supplies the first detection structure and the second detection structure in respective biasing time intervals, at least partially distinct from one another, which preferably do not temporally overlap one other.

  • Patent number: 9151806
    Abstract: A reading circuit for a magnetic-field sensor, generating an electrical detection quantity as a function of a detected magnetic field and of a detection sensitivity, is provided with an amplification stage, which is coupled to the magnetic-field sensor and generates an output signal as a function of the electrical detection quantity and of an amplification gain. In particular, the amplification gain is electronically selectable, and the reading circuit is moreover provided with a calibration stage, integrated with the amplification stage and configured so as to vary a value of the amplification gain in such a way as to compensate a variation of the detection sensitivity with respect to a nominal sensitivity value.
