Our speaker is  Domine M. W. Leenaerts , (NXP Semiconductors), and the topic of his presentation,  “WiMedia Ultra-Wide Band Communication”

Abstract
Abstract: Since the FCC opened up the spectrum for Ultra Wide Band (UWB) operation in the 3.1 to 10.6GHz range, several standards have been proposed to realize moderate and high rate short-range communication systems. Under the WiMedia umbrella, industry incorporated UWB as the technology to achieve high data rates up to 480Mbps for the wireless USB 2.0 applications. The WiMedia standard uses multi-band DCM/QPSK-OFDM modulated sub-bands of 528 MHz. A fast frequency-hopping scheme is applied to achieve efficient and robust communication links up to 10m distance. As the standard will be adopted by the cellular market, co-existence with other communication standards as GSM/WCDMA and WLAN/BT/GPS is an important but challenging system requirement.

Philips/NXP Semiconductors, Research is active in this field from the beginning of 2003. The presentation will give an overview how the UWB standard evolved and how the interesting research challenges were tackled (at least within Philips/NXP). In the early days the transceiver designs were developed in (SiGe) BiCMOS technologies with the focus on operation in band group 1 only, i.e. the frequency band from 3432MHz to 4488MHz. Later, the focus shifted towards CMOS designs targeting not only band group 1 but also band group 3 (6600MHz – 7656MHz) and even band group 6 (7656MHz – 8712MHz). Some insights in circuit design and measured performance will be provided during this presentation.

Biography

Domine M. W. Leenaerts received the Ph.D. degree in electrical engineering from Eindhoven University of Technology, Eindhoven, the Netherlands, in 1992. From 1992 to 1999, he was with Eindhoven University of Technology as an Associate Professor with the Micro-electronic Circuit Design group. In 1995, he was a Visiting Scholar with the Department of Electrical Engineering and Computer Science, University of California, Berkeley. In 1997, he was an Invited Professor at Ecole Polytechnique Federale de Lausanne, Switzerland. From 1999 to 2006 he has been a Principal Scientist with Philips Research Laboratories, Eindhoven, where he is involved in RF integrated transceiver design. In 2006, he moved to NXP Semiconductors, Research as Senior Principal Scientist in RF IC design.

He has published over 150 papers in scientific and technical journals and conference proceedings. He holds several US patents. He has coauthored several books, including Circuit Design for RF Transceivers (Boston, MA: Kluwer, 2001) Dr. Leenaerts served as IEEE Distinguished Lecturer in 2001-2203 and served as Associate Editor of the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS-PART I (2002-2004) and is since 2007 Associate Editor of the IEEE JOURNAL OF SOLID-STATE CIRCUITS. He is the IEEE Circuits and Systems Society Member representative in the IEEE Solid-State Circuits Society Administrative Committee since 2006. Dr. Leenaerts serves currently on the Technical Program Committee of the European Solid-State Circuits Conference (ESSCIRC), the IEEE Radio Frequency Integrated Circuits (RFIC), and IEEE International Solid-State Circuits Conference (ISSCC). Dr. Leenaerts is Fellow IEEE.
