Abstract
Described herein is an accelerometer that can be sensitive to acceleration, but not anchor motion due to sources other than acceleration. The accelerometer can employ a set of electrodes and/or transducers that can register motion of the proof mass and support structure and employ and output-cancelling mechanism so that the accelerometer can distinguish between acceleration and anchor motion due to sources other than acceleration. For example, the effects of anchor motion can be cancelled from an output signal of the accelerometer so that the accelerometer exhibits sensitivity to only acceleration.
