Abstract
On June 6th, 2023 at 10.00 am Antonio Liscidini, Professor at University of Toronto, Canada, will hold a seminar on "Quantized-Analog Signal Processing" in 25.0.1 Room (Building 25, Emilio Massa).
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 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.

Short Bio
Antonio Liscidini (Senior Member, IEEE) 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. He was an Assistant Professor with the University of Pavia from 2008 to 2012, and a Consultant with Marvell Semiconductors, Pavia, in the area of integrated circuit design. He moved to the Edward S. Rogers Sr. Department of Electrical and Computer Engineering, University of Toronto, Toronto, ON, Canada, in 2012, where he is currently a Full Professor. He was a Consultant with Huawei Technology Group, Shenzhen, China, from 2019 to 2022, in the area of RFIC for high-speed communication. He has become a consultant for Marvell Technology Group, Santa Clara, in 2022. 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 ultralow-power applications.
Dr. Liscidini was a recipient of the Best Student Paper Award at the IEEE 2005 Symposium on VLSI Circuits, and a co-recipient of the Best Invited Paper Award at the 2011 IEEE CICC and the Best Student Paper Award at the 2018 IEEE ESSCIRC. He is currently an Associate Editor of the IEEE Open Journal Of Solid State Circuit Society and IEEE Solid State Circuit Letters. He has served as an Associate Editor for the IEEE Transactions On Circuits And Systems-Part Ii: Express Briefs from 2008 to 2011 and 2017 to 2018 and as a Guest Editor for the IEEE Journal Of Solid-State Circuits in 2013 and 2016, and IEEE RFIC Virtual Journal in 2018. He has been a member of the ISSCC TPC from 2012 to 2017 and ESSCIRC TPC from 2010 to 2018, and has been a member of the CICC TPC since 2019. He was a Distinguished Lecturer of the IEEE Solid-State Circuits Society from 2016 to 2018.
