High Data Rate Analog to Digital Conversion for Wired/Wireless Communications Systems

March 30, 2012
2:00pm-3:00pm
Mudd 633
Hosted by: Columbia Integrated System Laboratory
Speaker: Dr. Mihai Sanduleanu (IBM T.J. Watson Research Center)

Abstract

Future Long Haul optics and high-density chip-to-chip I/O communication systems would require nonlinear equalization in the digital domain. With technology scaling and less analog options in modern CMOS technologies there is a clear evolution path towards ADC-DSP centric wired/wireless communication systems. The talk will address the design challenges and calibration techniques for high data rate ADCs realized in CMOS SOI technologies from IBM. Design trade-offs will identify fundamental limits and voltage domain / time domain analog-to-digital converter systems are discussed with their advantages and shortcomings.

Speaker Biography

Mihai Sanduleanu received the MSc degree in electrical engineering from "Gh. Asachi" University, Iasi, Romania in 1990 and the MEE degree from Eindhoven International Institute, Eindhoven, The Netherlands in 1994. In 1998 he received the PhD degree from University of Twente, Enschede, The Netherlands. In 1998 he joined the Fiber Optics Communication group from Philips Semiconductors, Nijmegen, The Netherlands. From 2000 until 2007 he conducted research on RF, mm-Waves and Fiber Optics communication circuits at Philips Research Eindhoven. From 2006 until 2007 he was part-time Professor at Eindhoven University of Technology, Eindhoven, The Netherlands in the Microelectronics Department. From 2008, he joined the Communication and Computation Department of IBM T.J. Watson Research Center. His current research interest is in high-speed analog CMOS circuits, mm-Waves and sub mm-Waves circuits. He is Associate Editor of IEEE Transactions on Circuits and Systems and member of the technical program committee of the Custom Integrated Circuits Conference (CICC).
