SUMMARY
This paper reports a new symmetric gyroscope
structure that allows not only matched resonant
frequencies for the drive and sense vibration modes for
better resolution, but also decoupled drive and sense
oscillation modes for preventing unstable operation
due to mechanical coupling. The symmetry and
decoupling features are achieved at the same time with
a new suspension beam design. The gyroscope
structure is designed using a standard three-layer
