Abstract

A technique includes using an accelerometer to provide an output signal indicative of an acceleration experienced by a movable mass of a sensor of the accelerometer. The technique includes testing the accelerometer, and the testing includes using a closed loop including the sensor to provide the output signal of the accelerometer; injecting a test signal into the loop between an output terminal of the sensor and an output terminal of the accelerometer; and indicating a performance of the accelerometer based on a response of the accelerometer to the injection of the test signal.
