As the boundaries between cyber and physical worlds blur, massive amounts of data are being generated and need to be received, stored, processed, and transmitted. Faster, smarter, and more reliable networks and devices are required to handle the variety and volume of data. On the other hand, after driving integrated circuit (IC) design for over 50 years, Moore’s law is running out of steam—technology scaling is slowing down; furthermore, it no longer leads to lower costs due to increasing design costs.
In this talk, I will explore a new pathway to address this increasing supply-demand imbalance from an IC designer’s point of view and, more importantly, to enable the next technological advance by leveraging the ongoing blurring interfaces between the digital and analog domains and the new wave of design methodology innovations. Starting from the IC design, I will discuss the application of intensive digital signal processing and mixed-signal techniques in analog/mixed-signal/RF circuit design for architectural-level breakthroughs with orders-of-magnitude improvement in system performance and flexibility. By effectively using time-domain signal processing and approximation, I made fundamental analog blocks more “digital-like,” which maximally leverages the fast devices offered by technology scaling and overcomes the limitations of advanced technology nodes (i.e., low supply voltages). I will present several benchmarking design examples of high-speed (>GS/s) data converters and RF/mm-wave transceivers with silicon prototypes and measurement results. Then, I will present novel design methodologies and flows for analog/mixed-signal/RF design automation, leveraging the
advancements of mostly digital circuit architectures and machine learning algorithms for considerably reducing chip design costs and iteration time. I will conclude the talk with my visions for new areas of research and applications enabled by these innovations in circuit architecture and design methodology.
