Prof. Michael Flynn Elected IEEE Fellow for Contributions to Analog-Digital Interfaces
- 12/08/2014
Prof. Michael Flynn has been elected IEEE Fellow, Class of 2015, for “contributions to analog-digital interfaces.” Prof. Flynn has achieved important breakthroughs in the performance and energy efficiency of analog-digital interfaces. His research has significantly impacted three primary areas: 1) analog to digital conversion; 2) the analog-digital interface in wired and wireless communication systems; and 3) applications to complete systems, particularly brain-machine interfaces.

New N-path filtering VCO presented by Chunyang Zhai at VLSI Symposium 2014
- 06/01/2014
A novel self-filtering scheme breaks the typical tradeoff between noise and power, enabling a ring oscillator to approach the phase noise performance of an LC oscillator.

New ring amplifier pipeline ADC structure presented by Yong Lim at ISSCC 2014
- 02/20/2014
This work improves the power efficiency and practicality of the ring amplifier by introducing a new self-biasing scheme and by eliminating the comparators. The prototype ADC has a measured of SNDR, SNR and SFDR of 56.3dB (9.06b), 56.7dB and 67.6dB, respectively, for a Nyquist frequency input sampled at 100MS/s and consumes 2.46mW, which results in a Figure-of-Merit of 46.1fJ/conv-step.
