Hidden behind the lay gaze upon every electronic device are integrated circuits that are hard at work. Going further down from there, now into the microscopic level, there are billions of undetectably tiny transistors magically configured to orderly fire signals at picosecond precision and microvolt resolution. This is where our subtle art of mixed-signal circuit design takes place.
We aim to launch hardware innovations by creating novel circuit structures/architectures that enable the most resource-efficient and high-performing chips. Our exploration expands to communication, computing, and sensing, among other applications. Focusing on the analog/mixed-signal aspect of circuit behaviors, we investigate the best way to harness the devices' promises and build them into valuable system features that impact people’s lives. And NO, op-amps and OTAs are NOT sufficient for every design we do.
In this talk, I will share our design pursuits in dynamic analogs and charge-domain circuits and discuss emerging opportunities in the mixed-signal IC domain. I wish to show how small qualitative changes in circuit construction can lead to solid quantitative gains and how those (seemingly incremental) quantitative gains could compound to bring about significant qualitative breakthroughs in the system.

Kyojin Choo heads the Mixed-Signal Integrated Circuits Lab (MSIC-Lab) in the Institute of Electrical and Micro Engineering (STI-IEM) at EPFL since late 2021. His team works on developing fundamental mixed-signal circuit techniques to apply in critical applications where better efficiency and performance are highly sought. He received his B.S. and M.S. from Seoul National University (Seoul, South Korea) and worked at Samsung (Yongin, South Korea), developing high-end image sensor products for DSLRs and mobile phones. Upon fulfilling his military service, he pursued his Ph.D. at the University of Michigan (Ann Arbor, MI, USA) and continued as a Post-Doctoral Fellow until he joined EPFL. He is active in the IEEE Solid-State Circuits Society.
