Integrated circuit design to enable highly miniaturized wireless sensing systems is coming at 05/13/2019 - 4:00pm
LINC 200 Mon, 05/13/2019 - 4:00pm Kannan A Sankaragomathi Senior hardware engineer , Google Inc Abstract: Several emerging applications such as healthcare sensing, ambient computing and Internet of Things demand highly miniaturized wireless sensors that are order-of-magnitude smaller than the current state of the art sensors. These next generation wireless sensors also need to be cheap, standards compliant and long lasting to enable widespread commercial adoption. Energy sources (i.e batteries) and frequency references (typically quartz crystal) are proving to be a critical bottleneck in achieving many of these goals. Intense circuit design research in the past decade has pushed the envelope in finding alternatives for batteries and the quartz crystal. In this talk I will discuss a few of the systems I have been fortunate to work on. a) A thin-Film Bulk Acoustic Resonator (FBAR) based quartz replacement. b) A 27uW optically powered ‘barely subcutaneous’ biosensing platform. c) A 0.004 mm3, 63 nW integrated circuit for an injectable glucose sensing system with optical power transfer d) A 1.5mm3 standards compliant, PLL-free BLE broadcaster module Bio: Read more: http://eecs.oregonstate.edu/colloquium/integrated-circuit-design-enable-...
