Patent ID: 11920958
Assignee: AMS AG
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 16:
17. A method for operating a sensor device, the method comprising
generating by means of an evaluation unit a stimulus signal;
providing the stimulus signal to a sensing unit;
generating by the sensing unit a measurement signal from the stimulus signal by adjusting an amplitude of the stimulus signal based on a measurement parameter; and
providing the measurement signal to the evaluation unit; and
generating by the evaluation unit an output signal based on the stimulus signal and the measurement signal;
wherein the method further comprises
generating by the evaluation unit a simulated measurement signal from the stimulus signal by controlling an amplitude of the stimulus signal based on a predetermined control variable;
generating a simulated output signal based on the stimulus signal and the simulated measurement signal; and
determining an error condition based on a comparison of the simulated output signal and the predetermined control variable or a signal derived from the predetermined control variable.
