The continuous feature size scaling in CMOS technology has enabled the system to decrease power consumption and lower costs while increasing reliability. The design of low-voltage opamp often poses significant challenges in the scaled CMOS technology. Dynamic amplifiers based on CMOS inverters attracts again and have become a necessity to minimize power consumption in all analog circuit blocks. This tutorial covers the design of energy-efficient inverter-based amplifiers, which includes recent advances to maintain the performance of analog circuitry. It also presents design examples of some state-of-the-art inverter-based amplifiers.

Youngcheol Chae received the Ph.D degree in electrical and electronic engineering from Yonsei University, Seoul, Korea in 2009. He is currently an Associate Professor at Electrical and Electronic Engineering Department, Yonsei University. From 2009 to 2011, he was a post doctoral researcher with the Electronic Instrumentation laboratory of Delft University of Technology in the Netherlands. After joining Yonsei since 2012, he leads the Mixed-Signal IC laboratory working on low-power data converters, high performance sensors and interface circuits. This results in more than 70 technical papers and 30 patents.

Dr. Chae received the Haedong Young Engineer Award from IEE Korea in 2017. He received the Outstanding Research Award from Yonsei University in 2017 and also received the Outstanding Teaching Award from Yonsei University in 2013 and 2014, respectively. He received a research grant from Samsung Research Funding Center in 2017 and a VENI grant from Dutch Technology Foundation STW in 2011. He is a member of the Technical Program Committees of International Solid-State Circuits Conference (ISSCC) and Asian Solid-State Circuits Conference (A-SSCC). He is a Distinguished Lecturer (DL) of IEEE Solid-State Circuits Society (SSCS).
