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

Claim 0:
1. A sensor front-end for processing a measurement signal from a sensing unit, the sensing unit being configured to receive a stimulus signal from an evaluation unit of the sensor front-end, generate the measurement signal from the stimulus signal by altering an amplitude of the stimulus signal based on a measurement parameter, and provide the measurement signal to the evaluation unit, the sensor front-end comprising the evaluation unit that is configured to
generate the stimulus signal;
generate an output signal based on the stimulus signal and the measurement signal received from the sensing unit;
generate a simulated measurement signal from the stimulus signal by controlling an amplitude of the stimulus signal based on a predetermined control variable;
generate a simulated output signal based on the stimulus signal and the simulated measurement signal; and
determine 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.
