Using a single mass structure with extra fingers for reading multiple axes allows better sensor performances when compared to multi-axis accelerometers with individual proof masses occupying the same die area. Test results show 274 mV/g scale factor for x-axis, and 280 mV/g scale factor for y-axis, while the cross-axis sensitivity for x-axis is calculated as 3.4 mV/g (% 1.26), and the cross-axis sensitivity for y-axis is -3.9 mV/g (% 1.4). Additionally, the bias instability values are measured as 22 μg and 23 μg, and the velocity random walk values are determined as 9.8μg/ √Hz and 9.9 μg/ √Hz for x and y axes, respectively. This sensing and readout approach can easily be adapted to achieve a high performance single mass 3-axis accelerometer in a small die area.","PeriodicalId":430128,"journal":{"name":"2015 IEEE International Symposium on Inertial Sensors and Systems (ISISS) Proceedings","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134453641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A finite element (FE) method is utilized to capture energy loss from the anchor. To eliminate wave reflection from the outer boundaries of the resonator substrate model, a perfectly matched layer is used. This artificial layer absorbs waves before they reach to the outer boundaries of truncated computational regions. Simulation results reveal that the resonators, which are connected to the thicker substrates show higher quality (Q) factor. It is found that among the modes, torsional mode is the most sensitive one to the substrate thickness. Such that as substrate thickness is increased 18 times, the Q-factor of the torsional mode is increased 6587 times. The results demonstrate that the Q-factor of the out-of-plane mode is also highly sensitive to the substrate thickness. However, the Q-factor of in-plane type modes is not as sensitive as other modes. The agreement between the simulation results and experimental data for anchor loss of cantilever type resonators validates the simulation method.","PeriodicalId":430128,"journal":{"name":"2015 IEEE International Symposium on Inertial Sensors and Systems (ISISS) Proceedings","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131635173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
