Assignee: ANALOG DEVICES, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 7:
8. A microelectromechanical systems (MEMS) accelerometer comprising:
a substrate disposed in a plane defined by a first axis and a second axis perpendicular to the first axis;
a first proof mass and a second proof mass coupled to the substrate and configured to translate in opposite directions of each other along a third axis perpendicular to the first and second axes, wherein the second proof mass is disposed within the first proof mass and the second proof mass is disposed between first and second anchors coupled to the substrate in a direction along the second axis; and
at least one lever coupling the first proof mass to the second proof mass, wherein:
the MEMS accelerometer is configured to detect acceleration along the third axis via detection of translation of the first and second proof masses along the third axis; and
the MEMS accelerometer exhibits symmetry about the first and second axes.
