Abstract: Sensor circuits having a filter and methods for filtering a sensor signal are provided. In this case, a passband width of an adjustable low-pass filter or bandpass filter is adjusted on the basis of a comparison of a measure of a signal change of a sensor signal with a threshold value.

Abstract: A sensor device includes a first sensor arrangement configured to generate first sensor signals based on sensing a varying magnetic field generated by a pole wheel having a pole wheel pitch, wherein the first sensor signals represent a first differential signal that defines a first measurement value; a second sensor arrangement configured to generate at least one second sensor signal based on sensing the varying magnetic field, wherein the at least one second sensor signal defines a second measurement value that is phase shifted from the first measurement value; and a signal processor configured to detect the pole wheel pitch based on the first measurement value and the second measurement value, and adjust a gain setting of an amplifier circuit based on the detected pole wheel pitch, where the amplifier circuit is configured to amplify the at least one second sensor signal.

Abstract: A magnetic sensor configured to detect a rotation of an object includes at least one sensor element configured to generate at least one sensor signal based on a magnetic field that is modulated by the rotation of the object; a sensor circuit configured to generate a data transmission signal based on the at least one sensor signal, wherein the data transmission signal comprises a plurality of data transmission blocks; and a memory configured to store transmission block status information indicative of whether or not one of the plurality of data transmission blocks has been triggered for transmission. The sensor circuit is configured to detect an interrupt event that disrupts the transmission of the data transmission signal and avoid a complete loss of a data transmission block due to the detected interrupt event based on the transmission block status information present at a time the interrupt event is detected.

Abstract: A control circuit is provided for a sensor that determines a sensed property. The control circuit includes an input interface configured to receive high-resolution data and low-resolution data for the sensed property. The control circuit further includes circuitry configured to determine information on a functional state of the sensor using the high-resolution data and the low-resolution data.
