High Efficiency Reconfigurable Monolithic Switched-Capacitor DC-DC Converter

The recent wireless sensing and emerging Internet-of-Thing (IoT) market have enabled the development of miniaturized systems with different application requirements. While highly efficient power management is mandatory to ensure the system performance and operation lifetime, on-chip inductive power converters generally exhibit increased manufacturing cost despite their higher achievable power densities. Due to the full integration together with high energy efficiency and adaptability, reconfigurable switched-capacitor (SC) DC-DC converters are promising for ultra-compact on-chip power solutions. This talk will first cover the basic operations and control methodologies of SC DC-DC converters. It will then introduce the conventional SC DC-DC topologies, followed by the fundamental analyses and different loss mechanisms. Advanced reconfigurable SC DC-DC converters capable of systematic multiple rational voltage conversion ratio (VCR) generation and their fundamental limits will also be proposed, and further compared with the state-of-the-art. Adaptive gate driving techniques with consistent switch driving voltage while preventing reversion loss under wide voltage dynamics will also be introduced. These techniques enable highly efficient SC power converters with better SoC integration for next generation ultra-compact low-cost IoT devices.


Man-Kay Law received the B.Sc. degree in computer engineering and the Ph.D. degree in electronic and computer engineering from the Hong Kong University of Science and Technology (HKUST), Hong Kong, in 2006 and 2011, respectively.

In 2011, he joined HKUST as a Visiting Assistant Professor. He is currently an Associate Professor with the State Key Laboratory of Analog and Mixed-Signal VLSI, Institute of Microelectronics, University of Macau, Macau, China. He has authored and co authored more than 90 technical publications, and holds six U.S./Chinese patents. His research interests are in the development of ultra-low-power CMOS sensing/readout circuits and energy harvesting (EH) techniques for wireless and biomedical applications.

Dr. Law is a TPC member of IEEE ISSCC. He is also the country representative of China for the ISSCC Far-East region in 2019.  He was a co-recipient of the ASQED Best Paper Award in 2013, the A-SSCC Distinguished Design Award in 2015, the ASPDAC Best Design Award in 2016, and the Macao Science and Technology Invention Award (Second Class) by Macau Government–FDCT in 2014 and 2018. He is also the advisor for student awards, including the SSCS Pre-doctoral Achievement Award and the ISSCC Silkroad Award.
