SSCS DL Presentation : Quantized-Analog Signal Processing
Abstract: Nowadays, both digital and analog electronics are reaching fundamental limits that will require revolutionary approaches to satisfy the power/bandwidth requirements of the next generation of data-driven applications. In the first part of the talk, analog and digital signal processing will be compared in terms of power efficiency by highlighting the presence of a thermodynamic upper-bound which relates dynamic range, bandwidth and power dissipation. To circumvent this limit, in the second part of the talk, the quantized-analog signal processing will be introduced. In such approach, analog and digital domains are merged together in a more fluid scenario compared to traditional mixed-signal circuits avoiding the needs of rigid interfaces such as analog-to-digital and digital-to-analog converters. It will be shown that the quantized-analog signal processing leads to superior power efficiency and flexibility compared to its analog counterpart and it represents a good candidate for the development of a new generation of mixed signal integrated circuits. The effectiveness of the proposed solutions will be demonstrated through simulations and measurement results. Antonio Liscidini received the Laurea (summa cum laude) and Ph.D. degrees in electrical engineering from the University of Pavia, Pavia, Italy, in 2002 and 2006, respectively. He was a summer Intern with National Semiconductors, Santa Clara, CA, USA, in 2003, studying poly phase filters and CMOS low-noise amplifiers. From 2008 to 2012, he was an Assistant Professor with the University of Pavia and a consultant with Marvell Semiconductors, Pavia, in the area of integrated circuit design. In 2012, he moved to the Edward S. Rogers Sr. Department of Electrical and Computer Engineering, University of Toronto, Toronto, ON, Canada, where he is currently Full Professor and Associate Chair Graduate. From 2019 to 2022 he was consultant for Huawei Technology Group in the area of RFIC for optical communication and SerDes. Since 2022 has been consultant for Marvell Technology group. His research interests are focused on analog mixed signal interfaces with particular emphasis on the implementations of transceivers and frequency synthesizers for wireless-wireline communication and ultra-low power applications. Dr. Liscidini was a recipient of the Best Student Paper Award at the IEEE 2005 Symposium on VLSI Circuits, co-recipient of the Best Invited Paper Award at the 2011 IEEE CICC and Best Student Paper Award at the 2018 IEEE ESSCIRC. He is currently Associate Editor in Chief for IEEE Transactions on Circuits and Systems II: Express Briefs. He has served as an Associate/Guest Editor for several IEEE Journal including: Open Journal of Solid-State Circuit Society, Transactions on Circuits and Systems II: Express Briefs and, Journal of Solid-State Circuits, RFIC Virtual Journal and Solid State Circuit Letters. He has been member for many TPC conferences including ISSCC, ESSCIRC, and CICC. Between 2016 and 2018, he has been a Distinguished Lecturer of the IEEE Solid-State Circuits Society. Since 2026, he is a IEEE Fellow.
