The proposed scheme actuates both gyroscope modes simultaneously with the same in-phase excitation, senses both modes concurrently, and utilizes the sum and difference of the sense signals to demonstrate complete cancellation of the gyroscope bias terms, and provide automatic in-run mode-matching capability. Moreover, the architecture provides twofold enhancement of angular rate sensitivity and signal-to-noise performance, as compared to conventional single-mode excitation of the same gyroscope. We demonstrate, for the first time 45× reduction in temperature drift of bias of a 2.6 MHz 650 μm diameter substrate-decoupled BAW gyroscope and a bias stability of 5.4 °/hr, paving the way towards near-zero-drift gyroscopes.","PeriodicalId":6465,"journal":{"name":"2015 Transducers - 2015 18th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79677271","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}

Besides the compact P-in-G architecture, the 1.25mm×1.25mm×0.45mm tiny-sized composite-sensor benefits from the single-wafer front-side fabrication technique.
