Abstract: The small signal levels provided by the limited size and inertial mass of miniature, open-loop MEMS accelerometers provide a challenging problem to achieve low noise and high stability needed for navigation and other applications. The challenge is made more difficult when different applications need to operate at a wide range of different peak g-levels. This paper discusses the performance achieved with six models of accelerometers recently introduced, built with a family of sense elements that optimize the sense element sensitivity to match the glevels needed. It shows the measured performance of models designed to cover a subset of the range from 2 to 100 G, and it shows how different error sources are reflected in the Allan Deviation curves for the different glevel accelerometers.
