Presentation Title：From Frequency to Time-Average-Frequency: A Paradigm Shift in the Design of Electronic System

Abstract :

Clock technology is one of the four fundamental technologies in the field of IC design. It is the timekeeper and the driver of everything inside a silicon chip. Time-Average-Frequency Direct Period Synthesis is an emerging technology in the field of on-chip frequency synthesis (clock generation). It comprises a new concept, a rigorous mathematical theory, and a novel circuit architecture. Its aim is the two long-lasting problems in this field: arbitrary frequency generation and instantaneous frequency switching (achieve them at the same time and at a reasonable cost). It is a component-level enabler for creating chip-system-architecture level innovations. Since clock is omnipresent in electronic system, this technology could introduce a paradigm shift in electronic system design. In this presentation, the Time-Average-Frequency concept will be explained. The circuit architecture will be briefly reviewed. Its impact, the route from component-level enabler to system level innovations, will be illustrated.

Biography :

Liming Xiu earned his B.S. and M.S. degrees in physics from Tsinghua University, Beijing, China, in 1986 and 1988, respectively.  Mr. Xiu earned his second M.S. degree in electrical engineering from Texas A&M University, College Station, TX, USA, in 1995. In 1990-1993, he was a research scientist of University of Houston, TX, USA. In 1995-2009, he worked for Texas Instruments Inc., Dallas, TX, USA (Senior Member Technical Staff). In 2009-2012, he was chief clock architect of Novatek microelectronics Corp., Hsinchu, Taiwan. Currently, he is involved in an IC design startup. He has 18 granted and 9 pending US patents and has published numerous IEEE journal papers and two books: VLSI Circuit Design Methodology Demystified (Wiley-IEEE Press) and Nanometer Frequency Synthesis beyond Phase-Locked Loop (Wiley-IEEE Press, IEEE Press Series on Microelectronic Systems). His third book From Frequency to Time-Average-Frequency: A Paradigm Shift in the Design of Electronic system (Wiley-IEEE Press, IEEE Press Series on Microelectronic Systems) will be published in May 2015. He is the inventor of Flying-Adder frequency synthesis architecture (Flying-Adder PLL). He served as vice president of IEEE Circuit and Systems Society in years 2009-2010.
