Abstract: Sensor devices and corresponding methods are provided. When a signal path output (COMP OUT) indicates no threshold crossings, diagnosis is performed with a timing based on a clock. In case threshold crossings are indicated, diagnosis is performed with a timing based on threshold crossings.

Abstract: A rotational angle sensor device and a corresponding method are provided. Two signals which have a phase offset with respect to one another are generated based on a modulated magnetic field using a sensor arrangement. Three signals which have a phase offset with respect to one another are generated from the signals.
