Abstract

An electronic device includes a resonant circuit and an evaluation circuit. The resonant circuit includes an acceleration-sensitive sensor which is excited to vibrate during a testing phase of the acceleration-sensitive sensor. The evaluation circuit is coupled to the resonant circuit to determine a performance reliability of the acceleration-sensitive sensor.
