MEMS Gyroscopes with Structurally Decoupled 2-DOF Drive and Sense Mode Oscillators

Acar C., Shkel A.M., University of California Irvine, US

This paper reports a novel 4 degrees-of-freedom (DOF) non-resonant micromachined gyroscope design concept that addresses two major MEMS gyroscope design challenges: eliminating the mode-matching requirement, and minimizing instability and drift due to mechanical coupling between [...]

A Design Approach for Robustness Improvement of Rate Gyroscopes

Acar C., Shkel A., University of California Irvine, US

This paper reports a design concept for robustness improvement of micromachined gyroscopes. The novelty of the approach is in expanding the design space of the device by increasing the degrees-of-freedom (DOF) of the system. The [...]

Modeling and Simulation of Micromachined Gyroscopes in the Presence of Imperfections

Shkel A., Howe R.T., Horowitz R., University of California-Berkeley, US

This paper studies behavior of non-ideal vibratory micromachined gyroscopes. The use of methods of motion decomposition [1] is the essence of the proposed analytical approach. The method is based on partitioning the equations of motion [...]
