Abstract
A system for diagnosing the operating state of a MEMS sensor includes a stimulation circuit, external to the MEMS sensor, configured to generate a stimulation signal designed to be detected by the MEMS sensor. The system has control circuitry, operatively coupled to the stimulation circuit and to the MEMS sensor, so as to control the stimulation circuit to generate the stimulation signal and receive a diagnostic signal generated by the MEMS sensor in response to the stimulation signal. The control circuitry determines an operating state of the MEMS sensor based on the diagnostic signal and an expected response to the stimulation signal by the MEMS sensor.
