| Abstract | This paper presents the fourth order vibratory micromachined gyroscope prototype with coupling forces between two modes and the coupling error expression which reveals all the factors affecting the amplitude of the error. A detailed discussion has been performed to determine that the diversity of structures of drive combs and sense combs is the main source of the Quality factor in drive mode varying from that in sense mode, and different frequencies in which coupling error centralizes with various air dampings. It is demonstrated that coupling error centralizes in the drive mode resonance frequency in 1 atmosphere while the error in sense mode resonance ascends in the presence of higher vaccum based on the experimental and fitting curves, and sense mode has almost the same error magnitude as drive mode in 782 mtorr vaccum with the measured data. The analysis of combs' effect on coupling error is significant for the optimization of comb structure, and provides a theoretical availability for the implementation of vaccum package and the greatly improved stability of MEMS gyroscopes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
