Abstract
A vibratory rate z-axis gyroscope is characterized by drive-mode and sense-mode quality factors and rate sensitivity and is fabricated with at least two decoupled vibratory tines, a levered drive-mode mechanism coupled between the tines to structurally force anti-phase drive-mode motion of the tines at a predetermined drive frequency, to eliminate spurious frequency modes of the anti-phase drive-mode motion of the tines lower than the predetermined drive frequency and to provide synchronization of drive- and sense-mode motion of the tines, and a sense-mode mechanism coupled between the tines arranged and configured to provide a linearly coupled, dynamically balanced anti-phase sense-mode motion of the tines to minimize substrate energy dissipation and to enhance the sense-mode quality factor and rate sensitivity.
