摘要：
Influence of fabrication errors on modal amplitude in a dual-mass silicon micro-gyroscope is present in this paper. Firstly, the structure and operation principle a dual-mass silicon micro gyroscope is introduced. Then the equation of amplitude ratio between left and right proof mass is deduced. Finally, the simulation analysis of fabrication errors on modal amplitude is implemented. The simulation results show the amplitude ratio is decreased to -1.2741 when the left proof mass error is 5% in anti-phase driving mode. The amplitude ratio is increased to -0.800 when the left stiffness error is 5% in anti-phase sensing mode.
