| Popis: | We present the design and analysis of a mode-matched disk resonator gyroscope that is characterized by a high quality factor exceeding 1 million. The mode match resonator is designed using geometric compensation technique for reducing frequency split between two degenerate modes. The gyroscope sensor is designed using MEMS Integrated Design for Inertial Sensors (MIDIS) process offered by Teledyne DALSA Semiconductor Incorporated (TDSI). The MIDIS process offers ultra clean wafer-level vacuum encapsulation at 10m Torr. Our disk resonator gyroscope has a circular shape with 600 μm diameter and is made with 40 μm thick single crystal silicon material. |
