Combining\u0026nbsp;such devices into a multi-degree-of-freedom inertial measurement unit (IMU) on a single-chip enables the simultaneous measurement of pulmonary lung sounds, chest wall motion,\u0026nbsp;heart mechano\u0026nbsp;acoustic signals, as well as of user body motion. The CMOS ASIC for the\u0026nbsp;acoustic IMU consists of switched capacitor and transimpedance amplifier front-end\u0026nbsp;circuits that utilize\u0026nbsp;correlated double sampling and chopping for the dynamic cancellation\u0026nbsp;of offset and flicker noise, and use charge injection calibration techniques to compensate\u0026nbsp;for MEMS capacitor mismatch. For tuning and alignment of gyroscopic resonators, low-noise high-voltage (20V)\u0026nbsp;charge pumps are implemented on-chip. We discuss the prospects\u0026nbsp;of reducing power while maintaining precision in interface ICs for MEMS IMUs and\u0026nbsp;review a few IoT applications of these devices.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EBiographical Sketch of the Speaker:\u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFarrokh Ayazi is the Regents Entrepreneur, and the\u0026nbsp;Ken Byers Professor in Microsystems in the School of Electrical and Computer\u0026nbsp;Engineering at Georgia Tech, where he has been a member of the academic faculty since\u0026nbsp;January 2000. During his career at Georgia Tech, he has graduated 32 Ph.D. students and\u0026nbsp;advised 21 postdoctoral fellows and research\u0026nbsp;engineers. He is currently also the founder at\u0026nbsp;StethX Microsystems, a spin-off of his research lab that is developing next-generation wearable devices for long-term monitoring of cardio-pulmonary diseases using\u0026nbsp;a proprietary microchip sensor technology. Prior to StethX, Dr.\u0026nbsp;Ayazi was founder and CTO\u0026nbsp;of Qualtr\u0026eacute;, another spinout of his research lab that develops\u0026nbsp;bulk acoustic wave gyroscopes for\u0026nbsp;autonomous car and personal navigation systems, which was acquired by Panasonic in\u0026nbsp;2016. Dr. Ayazi is a fellow of IEEE and holds 65 patents. He was the general chair of the\u0026nbsp;IEEE Micro-Electro-Mechanical-Systems (MEMS) conference in 2014, held in San\u0026nbsp;Francisco, CA. He also served on the technical program committee of the IEEE\u0026nbsp;International Solid State Circuits Conference (ISSCC) for six years. Dr. Ayazi was the\u0026nbsp;recipient of the campus wide Outstanding Achievement in Research Innovation Award\u0026nbsp;from Georgia Tech in 2018.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EECE Professor Farrokh Ayazi\u0026nbsp;will deliver the Nov. 7 ECE Student Seminar,\u0026nbsp;\u0026quot;Integrated CMOS-MEMS Acoustic Microsystems for\u0026nbsp;Health Informatics and IoT.\u0026quot;\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Featuring ECE Professor Farrokh Ayazi"}],"uid":"36172","created_gmt":"2022-10-28 13:30:20","changed_gmt":"2022-10-28 14:30:24","author":"dwatson71","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2022-11-07T12:30:00-05:00","event_time_end":"2022-11-07T13:20:00-05:00","event_time_end_last":"2022-11-07T13:20:00-05:00","gmt_time_start":"2022-11-07 17:30:00","gmt_time_end":"2022-11-07 18:20:00","gmt_time_end_last":"2022-11-07 18:20:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[],"keywords":[{"id":"5617","name":"ECE Student Seminar"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:mary.ann.weitnauer@ece.gatech.edu\u0022\u003EMary Ann Weitnauer\u003C\/a\u003E\u003Cbr \/\u003E\r\nSchool of Electrical and Computer Engineering\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
