Foster Dai - Advances in Analog-to-Digital Converters and Phase-Locked Loops
Abstract: Analog-to-digital converter (ADC) and phase-locked loop (PLL) integrated circuits (ICs) play critical roles for the implementations of modern communication transceivers. The next-generation wireless connectivity holds unforeseen challenges with ever increasing demands on low latency, low power, and wide bandwidth. With technology scaling, traditional signal processing in voltage domain becomes increasingly difficult when high dynamic range and high linearity are required. This talk addresses the challenges in high-performance ADC and PLL IC designs in deep-submicron technologies. We present our recent research results on the time-domain quantization for low-power ADCs and the CDAC-based spur cancellation for high-performance PLLs. The proposed low power ADC and PLL technologies can achieve superior power efficiency for emerging applications such as 5G, automobile radar, smart machines, IoT and digital health.

Fa Foster Dai of Department of Electrical and Computer Engineering, Auburn University, USA
Biography:
Fa Foster Dai received a Ph.D. degree from The Pennsylvania State University. He currently holds the Godbold Endowed Chair Professor position at the Electrical and Computer Engineering Department of Auburn University. Prior to his joining Auburn in 2002, he spent 6 years in industry, working as the lead RFIC engineer and technical manager for companies such as Hughes Electronics, Yafo Networks and Cisco-Cognio.
Dr. Dai served as Guest Editor for IEEE Journal on Solid State Circuits and IEEE Transactions on Industrial Electronics. He has served on the technical program committees (TPCs) of IEEE Symposium on VLSI Circuits, IEEE Bipolar / BiCMOS Circuits and Technology Meeting and IEEE Custom Integrated Circuits Conference. He is currently on the TPC of IEEE Radio Frequency Integrated Circuits Symposium. He was the 2016 TPC Chair and the 2017 General Chair of IEEE Bipolar / BiCMOS Circuits and Technology Meeting. He served as the 2019 TPC Chair, the 2020 Conference Chair and the 2021 General Chair of IEEE Custom Integrated Circuits Conference. Dr. Dai received the Senior Faculty Research Award for Excellence from Auburn University in 2009 and was awarded the Distinguished Graduate Faculty Lectureship from Auburn University in 2021. He received IEEE Region 3 Outstanding Engineer Award in 2023. He holds 17 U.S. patents and was elected to the Fellow of National Academy of Inventors in 2021. He was elected to the IEEE Fellow in 2009 “for contributions to high-speed frequency synthesis and radio frequency integrated circuits”.
