Abstract
Systems and methods are provided for monitoring operation of MEMS accelerometers (100). In these embodiments a control loop (112) having a forward path (114) is coupled a MEMS transducer (110), and a test signal generator (124) and test signal detector (126) is provided. The test signal generator (124) is configured to generate a test signal and apply the test signal to the forward path (114) of the control loop (112) during operation of the MEMS accelerometer transducer (110). The test signal detector (126) is configured to receive an output signal from the control loop and detect the effects of the test signal in the output signal. Finally, the test signal detector (126) is further configured to generate a monitor output indicative of the operation of the sensing device to provide for the continuous monitoring of the operation of the MEMS accelerometer (100).
