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 on RF-analog front-ends.


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 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.
