Title: A 16-Gb/s Near-Ground Transceiver with Receive Replica Transconductance Termination Calibration

Organizer:

This event is organized by CAS society and co-sponsored by SSC chapter.

Speaker: Kambiz Kaivani, Rambus Inc.

Abstract:

In this talk a bi-direction differential low-common mode source-series-terminated transceiver operating up to 16-Gb/s data rate is presented. The transceiver is equipped with a number of novel architecture and circuit ingredients to enable reliable data communication over a band-limited channel while maintaining low power efficiency. Specifically, a compact voltage-mode driver and equalizer in the transmitter, and a calibrated fast-response decision feedback equalizer in the receiver are deployed to compensate channel inter-symbol interference. Also, the receiver employs a replica transconductance termination calibration to terminate the communication channel accurately in presence of the receiver input loading. The receiver further incorporates common mode to differential gain cancellation and in-situ equalization calibration for reliable data reception at 16Gb/s over a 3” FR4 PCB memory link with 15dB loss at Nyquist frequency.

Biography:

 Kambiz Kaviani received the B.S. degree from Sharif University of Technology, Tehran, Iran, in 1994, and the M.S. and Ph.D. degrees from Stanford University, Stanford, CA, both in electrical engineering, in 1999 and 2003, respectively. He is currently a Principal Engineer at Rambus Inc., Sunnyvale, CA, developing high-performance data interface technologies for SERDES, XDRTM, DDR, LPDDR and GDDR platforms. During the summer of 1998, he was with RadioLAN Corporation, Sunnyvale, CA, where he was involved in wireless local area network (WLAN) developments. At Stanford, he was focusing on high-speed and high-precision VLSI data converters and macro-electro-mechanical systems (MEMS). His main interests include high-performance CMOS mixed-signal and RF integrated circuits and systems. Dr. Kaviani was a co-recipient of the 2002 outstanding paper award of the IEEE Ultrasonic, Ferroelectrics, and Frequency Control Society and 2008 CICC best paper award. He has authored or coauthored more than twenty technical papers and patent applications and was a member of the Iranian team in the 21st international Physics Olympiad, Groningen, The Netherlands.
