Abstract / Description: 

The trend of modern electronic systems, such as wireless and wireline applications, demands increasing reconfigurability, bandwidth, and dynamic range, but low power and cost. On the other hand, the technology scaling is slowing down its pace and incurs significant cost particularly for analog designs. Those factors have driven the design community to pursue both new circuit and system architectures towards unprecedented flexibility, performance, and low cost. Wouldn’t it be nice to have an electronic system that can be arbitrarily configured based on user’s needs? In this talk, we will examine several such attempts recently demonstrated by our group members that show the importance/effectiveness of re-thinking the analog-digital boundary in both circuit and system level towards this goal. Several initial silicon prototypes achieve encouraging performance and flexibility in comparison with the state of the arts. More importantly, they tout the potential for many future extensions, and hopefully allow a different thinking for analog-digital interface circuit architecture to transform future electronic system designs.


Mike Shuo-Wei Chen received the B.S. degree from National Taiwan University in 1998, and the M.S. and Ph.D. degree from the University of California, Berkeley in 2002 and 2006, all in Electrical Engineering. As a graduate student, he proposed and demonstrated the asynchronous SAR ADC architecture, which has already been adopted today in industry. Since 2006, he has been working on mixed-signal and RF circuits for various wireless standards at Atheros communications (now Qualcomm-Atheros). He joined EE department at University of Southern California since 2011, and currently holds Colleen and Roberto Padovani Early Career Chair position. His research group is having fun with exploring the limit of analog mixed-signal, RF ICs, Bio-inspired electronics, and signal processing techniques for circuits and systems.

Dr. Chen received an honourable mention in the Asian Pacific Mathematics Olympiad, 1994. He was the recipient of NSF Faculty Early Career Development (CAREER) Award, DARPA Young Faculty Award (YFA) both in 2014, UC Regents’ Fellowship at Berkeley in 2000 and Analog Devices Outstanding Student Award for recognition in IC design in 2006.
