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.
