Abstract
Embodiments of the invention include an accelerometer system. The system includes an accelerometer sensor comprising first and second electrode configurations and an inertial mass between the first and second electrode configurations. In one example, the accelerometer sensor being fabricated as symmetrically arranged about each of three orthogonal mid-planes. The system also includes an accelerometer controller configured to apply control signals to each of the first and second electrode configurations to provide respective forces to maintain the inertial mass at a null position between the first and second electrode configurations. The accelerometer controller can measure a first pickoff signal and a second pickoff signal associated with the respective first and second electrode configurations. The first and second pickoff signals can be indicative of a displacement of the inertial mass relative to the null position. The accelerometer controller can calculate an acceleration based on the first and second pickoff signals.
