Abstract:The eigenfrequency of a MEMS Tuning Fork Gyroscope (TFG) is calculated using a formula derived from Rayleigh method. From this formula, the objective function for the optimal design is established. Then two methods to solve the objective function are introduced. The TFG has also been fabricated using SOI technologies based on the optimum design. Driving testing results show good agreement between the calculated and the experimental eigenfrequencies.
