T-4 Fully-Integrated Voltage Regulators: From Single Point to 2-D Distribution

Prof. Yan Lu
University of Macau, Macau, China

Abstract:
Fully-integrated voltage regulators (FIVRs) enable fast dynamic voltage and frequency scaling for energy-efficient high-performance digital systems. This tutorial will cover the fundamentals of low-dropout (LDO) regulators and switched-capacitor (SC) converters. Emphasis will be put on design considerations of analog/digital/mixed control, PID control for FIVR, and resonant SC converter. Last but not least, we will have discussions on the distributed FIVR designs for large-scale digital load, including our design examples on the ring-shaped multi-phase SC converters with unity-gain bandwidth beyond the switching frequency, and the switching LDOs with fast transient, good power supply rejection, and scalable load capability.

Prof. Yan Lu

Yan Lu received his BEng and MSc degrees from South China University of Technology, Guangzhou, China, in 2006 and 2009, respectively, and the PhD degree in Electronic and Computer Engineering from the Hong Kong University of Science and Technology (HKUST), Hong Kong, China, in 2013.

Since 2014, he has been with the State Key Laboratory of Analog and Mixed-Signal VLSI, University of Macau, where he is now an Associate Professor. He has authored/coauthored more than 100 peer-reviewed technical articles and one book entitled “CMOS Integrated Circuit Design for Wireless Power Transfer” (Springer), and holds 3 China patents and 2 US Patents. His research interests include fully-integrated voltage regulators, DC-DC converters, and wireless power transfer circuits and systems.

Dr. Lu is serving as a TPC Member for ISSCC and CICC, and a Youth Editor of the Journal of Semiconductors. He was a recipient/co-recipient of the Macao Science and Technology Award 2018 and 2020 (both second prize, 2018 with the first prize vacancy), the IEEE Solid-State Circuits Society Pre-doctoral Achievement Award 2013–2014, the IEEE CAS Society Outstanding Young Author Award 2017, and the ISSCC 2017 Takuo Sugano Award for Outstanding Far-East Paper.
