Abstracts:
Biomedical and healthcare applications provide attractive opportunities for the semiconductor sector. In both fields, the target is to gather data from multiple sensor nodes with minimal power consumption while maintaining low noise operation. However, designing a sensor interface circuit for such applications is challenging due to its harsh environment. Also, in such cases, the trade-off between available resources and performance among the components both in analog front-end and in the digital back-end is crucial.
Ultrasound Imaging System (UIS) has been widely used in medical imaging with its non-invasive, non-destructive monitoring nature; but so far the UIS has large form factor, making it difficult to integrate in mobile form factor. For drone and robotic vision and navigation, low-power 3-D depth sensing with robust operations against strong/weak light and various weather conditions is crucial. CMOS image sensor (CIS) and light detection and ranging (LiDAR) can provide high-fidelity imaging. However, CIS lacks depth sensing and has difficulty in low light conditions. LiDAR is expensive with issues of dealing with strong direct interference sources. UIS, on the other hand, is robust in various weather and light conditions and is cost-effective. However, in air channel, it often suffers from long image reconstruction latency and low framerate.
Bio: Jerald Yoo (S’05-M’10-SM’15) received the B.S., M.S., and Ph.D. degrees in Department of Electrical Engineering from the Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea, in 2002, 2007, and 2010, respectively. From 2010 to 2016, he was with the Department of Electrical Engineering and Computer Science, Masdar Institute, Abu Dhabi, United Arab Emirates, where he was an Associate Professor. From 2010 to 2011, he was also with the Microsystems Technology Laboratories (MTL), Massachusetts Institute of Technology (MIT) as a visiting scholar. Between 2017 and 2024, he was with the Department of Electrical and Computer Engineering, National University of Singapore, Singapore, as an Associate Professor. Since 2024, he has been with the Department of Electrical and Computer Engineering, Seoul National University, where he is currently an Associate Professor.
