ABSTRACT:
A dual-axis accelerometer and processing circuit are provided. The accelerometer has a plurality of fixed electrodes supported on a substrate and fixed capacitive plates arranged in first and second sensing axes. An inertial mass is suspended over a cavity and includes movable capacitive plates arranged to provide a capacitive couplings with the fixed capacitive plates. The inertial mass is movable relative to the plurality of fixed electrodes. The accelerometer has a plurality of support arms for supporting the inertial mass relative to the fixed electrodes and allowing movement of the inertial mass upon experiencing acceleration along the first and second sensing axes. The accelerometer further has inputs for receiving input signals and an output for providing an output signal which varies as a function of the capacitive coupling and is indicative of sensed acceleration. The processing circuit extracts the components of acceleration along the first and second sensing axes.
