Colloquium Series

Once every week while school is in session, EECS invites a distinguished researcher or practitioner in a computer science or electrical and computer engineering-related field to present their ideas and/or work. Talks are generally targeted to electrical engineering and computer science graduate students. This colloquium series is free and open to everyone.

Zooming in on ADC Efficiency

Abstract

Today, the most energy-efficient ADCs are based on either successive approximation or on ΣΔ modulation. SAR ADC’s are more energy efficient, while ΣΔ ADCs can achieve higher resolution. In this talk, it will be shown how both high energy efficiency and high resolution can be achieved by combining both these approaches in a so-called zoom ADC. As a case study, the design of a state-of-the-art zoom ADC will be presented. It achieves 107.5dB DR and 104.4dB SNR in a 20kHz bandwidth while dissipating only 1.65mW and occupying only 0.16mm2.

Speaker Bio

Kofi A.A. Makinwa is a Professor at Delft University of Technology, The Netherlands, where he leads a group that designs precision analog circuits, ΣΔ modulators, and smart sensors. He holds B.Sc. and M.Sc. degrees from Obafemi Awolowo University, Nigeria, an M.E.E. degree from the Philips International Institute and a Ph.D. degree from Delft University of Technology, both in The Netherlands. From 1989 to 1999 he was a research scientist at Philips Research Laboratories. He holds 22 patents, and has (co)-authored some 200 technical papers and 6 books, and has co-edited 4 more. Dr. Makinwa is a (co)-recipient of JSSC (2), ISSCC (4), Transducers, and ESSCIRC best paper awards, among others, and is a recipient of the Simon Stevin Gezel award from the Dutch Technology Foundation. He currently serves on the program committees of ISSCC, VLSI, ESSCIRC and AACD, and is also a member of the SSCS Adcom. He is an IEEE Fellow, a former IEEE distinguished lecturer and an alumnus of the Young Academy of the Royal Netherlands Academy of Arts and Sciences.
