The vibration behavior of a hemispherical resonant gyro (HRG) and a microring-gyro made of {111} silicon wafer are studied. It was found that for HRG, the persisting vibration does not exist for the linear model but exists for the nonlinear one; whereas it exists in the linear model for micro-gyro, this is due to the size effect. The relationships between the angular velocity and the output vibrating magnitudes of both gyros are derived analytically by using perturbation technique.
