Prof. Yue interacted closely with the audience before and after the sessions. including custom CMOS images, whereas VLC transmitters have been predominately based on discrete implementation until recently. More importantly, the power consumption of dedicated VLC transmitters is prohibitively high with bit efficiency in the 100-nJ/b range. To overcome these issues, this talk describes the first fully integrated VLC transmitter SoC compliant with the IEEE 802.15.7 standard embedded with a built-in 8-W LED driver. Excluding the power consumed by the LED driver, the SoC achieves a r e cor d VLC transmission efficiency of 5 nJ/b. Furthermore, the miniaturization and integration of inorganic LED display modules have attracted significant research efforts due to their superior brightness and reliability compared to organic LED microdisplay. Combining these two technology trends, this talk also describes an active matrix LED driver SoC with built-in VLC modulation capability to demonstrate a wide quarter video graphics array smart microdisplay featuring 1.25-Mb/s VLC for enabling LED digital signage as location-based information broadcaster and indoor positioning beacons. Lecture attendees listen intently to Prof. Yue's talk. -Jianhua Jiang SSCS DL Program Organized by Thailand Section T The IEEE Solid-State Circuits Society Thailand Chapter invited Distinguished Lecturer (DL) Prof. Jerald Yoo from the National University of Singapore to give a talk on two advanced Digital Object Identifier 10.1109/MSSC.2017.2769321 Date of publication: 31 January 2018 52 w i n t e r 2 0 18 topics regarding wearable technology. Yoo presented "Body Area Network" and "Design Strategies for Wearable Sensor Interface Circuits." The event was held at the Mahanakorn University of Technology on 7 August 2017. During the talk, Yoo described several techniques to design a low- IEEE SOLID-STATE CIRCUITS MAGAZINE noise, high-input impedance, high common-mode rejection ratio operational amplifiers suitable for measuring body signal with very large common mode signal from power line. He also described the human body characteristics as a signal transmission medium for the application to intrabody communication.
