    Abstract: An inductive sensor may include a first angle measurement path associated with determining an angular position based on a first set of input signals. The inductive sensor may include a second angle measurement path associated with determining an angular position based on a second set of input signals. The inductive sensor may include an amplitude regulation path associated with regulating amplitudes of a set of output signals. The inductive sensor may include a safety path associated with performing one or more safety checks. Each safety check of the one or more safety checks may be associated with at least one of the first angle measurement path, the second angle measurement path, or the amplitude regulation path.

    Abstract: An apparatus for monitoring a signal path is provided. The signal path includes a first processing unit, which generates a first signal based on an input signal of the signal path, and a second processing unit, which generates an output signal of the signal path, wherein the output signal depends on the first signal. The apparatus includes an output estimation module configured to determine an estimated output signal of the second processing unit based on the input signal. Further, the apparatus includes a comparison module configured to determine a state of the signal path based on a deviation of the output signal from the estimated output signal.

    Abstract: An angle sensor may include a first angle measurement path to determine an angular position based on sensor values from a first set of sensing elements. The angle sensor may include a second angle measurement path to determine the angular position based on sensor values from a second set of sensing elements. A type of the second set of sensing elements is different from a type of the first set of sensing elements. The angle sensor may include a safety path to perform a set of safety checks, the set of safety checks including a first vector length check associated with the first angle measurement path and a second vector length check associated with the second angle measurement path. The angle sensor may include an output component to provide an indication of a result of the set of safety checks.
