TW1: An Introduction to Bluetooth: A Standard for Short-range Wireless Networking
Prof. Dennis Sweeney, Virginia Tech Center for Wireless Telecommunications

Bluetooth is an emerging standard for short-range low-cost wireless connectivity for consumer devices and Personal Area Networks (PAN). It is a frequency hop spread spectrum system intended for worldwide operation in the unlicensed 2.45 GHz Industrial Scientific Medical (ISM) band. Bluetooth is more than just a radio; it is an entire networking standard. This tutorial will provide a look under the “logo” at the basic structure of Bluetooth, its capability to transmit both voice and data, and its software “stack.” It will also examine interference issues and some of the resources available for developing Bluetooth applications.

Prof. Sweeney is with the Center for Wireless Telecommunications (CWT) at Virginia Tech. His interests are in unlicensed wireless applications, Local Multipoint Distribution Services (LMDS), and radio frequency circuit design. He directs the CWT’s RF Design Lab. This lab has been involved in the design of 900 MHz spread spectrum communications system and a 3-G test bed radio. In addition to RF circuit design, Dr. Sweeney’s interests include microwave propagation including satellite slant path propagation and propagation for wireless applications. His current project is a short pulse channel sounder for LMDS. Dr. Sweeney worked on Global Positioning System (GPS) receiving equipment and applications at the Jet Propulsion Laboratory in Pasadena, CA. He teaches both undergraduate and graduate courses in Radio Engineering, electronics and satellite communications, and short courses on filter design and unlicensed wireless.

TW2: SoC Signal Integrity and Power Delivery Design Challenges and Solutions
Prof. Charlie Chen, University of Wisconsin

This tutorial presents signal integrity and power delivery design challenges and possible solutions for high-speed, low power, deep sub-micron, and millions-of-transistors SoC VLSI design. Starting from technology scaling trends, several signal integrity issues such as capacitance and inductance modeling, electrical and magnetic coupling noises, and their impacts to timing will be discussed. Novel signal integrity analysis algorithms, optimization methods, and design methodology will be presented. Power delivery issues such as IR drop, Ldi/dt drop, and packaging resonance problems will also be discussed in detail. Several comprehensive power delivery design methodology and efficient analysis techniques will also be presented.

Charlie Chung-Ping Chen received his B.S degree in computer science and information engineering from the National Chiao-Tung University, Hsinchu, Taiwan, in 1990 and his M.S. and Ph.D. degrees in computer science from the University of Texas at Austin in 1996 and 1998. From 1997-1999 he was with Intel Corporation as a senior CAD engineer with Strategic CAD Labs. He was in charge of several interconnect and circuit synthesis projects in the micro-processor group. Currently, he is an assistant professor in the ECE Department at the University of Wisconsin, Madison. His research interests are in the areas of computer-aided design and microprocessor circuit design with an emphasis on interconnect and circuit optimization as well as signal integrity analysis and optimization. Prof. Chen received the D2000 award from Intel Corp. and National Sciences Foundation Faculty Early Career Development Award (CAREER) at 1999 and 2001, respectively.

TW3: Low-Voltage Current-Mode Analog Circuit Structures and Applications
Prof. Sudhanshu Jamuar, Indian Institute of Technology, New Delhi, India

This tutorial presents an overview of techniques used for low-voltage, low-power analog circuit structures. Brief details of prevalent techniques such as bulk-driven transistors, sub-threshold transistors, and level shifter transistors will be presented along with their merits and demerits. Advanced current mirrors and voltage buffers, signal processing cells, and applications in analog signal processing and other specialized signal processing applications are explored in detail.

Prof. Sudhanshu Jamuar received his PhD from the Indian Institute of Technology, Kanpur, India, in 1977. Since 1977, he has been with the Indian Institute of Technology, New Delhi, where he is presently a full professor and leads research on analog/digital circuits and communication systems. He is a Fellow of the Institute of Electronics and Telecommunications, India.

TW4: Low-noise Systems on Chip for 3G Wireless
Dr. Sam Martin and Dr. Michael Heutmaker, Bells Labs, Lucent Technologies

This workshop addresses issues of strong current interest in developing high performance SoC devices for wireless applications. An overview of system aspects of wireless voice/data communications, highlighting 3G/4G cellular is provided.  Trends in the development of 3G wireless communication systems will be discussed with emphasis on low noise SoC design challenges, such as DC to RF migration, mixed-signal and noise interference/substrate cross-talk issues.   

Samuel Martin received his M.S. and Ph.D. Degrees in Condensed Matter Physics from the University of Frankfurt in West Germany and then joined AT&T Bell Labs in 1987.  He is presently a distinguished member of technical staff in the Semiconductor Physics Research Department at Bell Laboratories, Lucent Technologies in Murray Hill, NJ. He has worked on developing low frequency flicker noise measurement methods and on measurements and modeling of RF noise properties of various semiconductor device technologies used in wireless applications.  He is presently involved in the RFIC integration of next generation base station products.  He holds six patents and has contributed to over 60 publications as well as to over 50 technical talks.

Michael Heutmaker joined Lucent Technologies (then AT&T) in 1986 after receiving a Ph.D. in Physics from the University of Pennsylvania. He has worked in wireless test and product development since 1990, and presently specializes in the measurement and analysis of digitally-modulated signals in wireless systems and circuits. Mike holds six patents and has published approximately 15 papers. Since 1997 he has been Technical Program Chair and/or General Chair of the IEEE Radio and Wireless Conference (RAWCON).
