"Dynamically Adaptive Power Supply Circuits for Radio-Frequency (RF) Power Amplifier (PA) Applications" by Gabriel A. Rincón-Mora, sponsored by the IEEE Circuits and Systems Society, the IEEE Microwave Theory & Techniques Society, and the IEEE Solid State Circuits Society The role of Radio-Frequency (RF) Power Amplifiers (PAs) in today's and tomorrow's consumer and state-of-the-art electronics is crucial, catering to the stringent performance (i.e., linearity and output power) and real-estate (i.e., size) requirements of portable systems and the power limitations of battery-powered applications. Key to the success of any portable device is battery life (or runtime), and PAs can be a significant and detrimental load in this regard, especially because they capture a significant portion of the total power budget and they characteristically have poor power efficiencies. This course will address the advent of dynamically adaptive biasing schemes in PA applications to increase power efficiencies, which is generally done by essentially transforming and redefining the operating environment of the PA for maximum performance at optimum power levels, and consequently prolonging battery life. After completing this course you should be able to develop an understanding of:

"Home Networking Standards" by Marie-José Montpetit sponsored by the IEEE Communications Society In recent years the converging digital technologies of television, publishing, telephony and computers, the so-called multimedia revolution, have prompted the deployment of a multitude of high-speed applications from streaming video to the World Wide Web to deskTop video editing. An immediate impact of this evolution is the ever-increasing demand for Internet bandwidth, the more intelligent use of already available resources and the use of overlay networks in the home. Because of the emergence of the home networks, the nature of networking itself is changing dramatically. It is moving away from supporting mainly home business and education applications and into the infotainment world where video and audio are now predominant and IPTV is emerging as the “killer app”. In this environment the all-IP network is emerging as the network layer of choice. Hence in Internet terms the home becomes another subnet. But IP does not describe the whole Home Networking solutions. What are also needed are technologies to transport the information and software and middleware to enable the development of those solutions that will allow the Home Network to be “user friendly”. After completing this course you should be able to develop an understanding of:

In response to both the wireless industry’s need to perform advanced product testing and consumer demand for high quality 802.11 devices, a new testing specification, IEEE 802.11.2, is being developed by the 802.11 Task Group T. 802.11.2 incorporates test methods and metrics for roaming, voice and video quality, power consumption, throughput performance and other important parameters. These advances in test methodology are required to improve the quality of 802.11 solutions and enable reduction in design cycles. Voice applications, for example, have pushed the 802.11 industry to specify several new protocols including 802.11r fast roaming, 802.11e quality of Service (QoS) and power-save. New applications that carry both voice and video over 802.11 have stringent performance requirements that can only be guaranteed by thorough and methodical testing. This course will provide an in-depth look at the performance requirements of the demanding voice and video applications. We will examine how these applications perform today and will look at the improvements offered by the emerging 802.11n standard. We will discuss performance, security and power conservation issues in the context of mesh network architecture being introduced by the emerging 802.11s specification. Finally, we will examine the test methods and metrics currently in the 802.11.2 recommended practices document and will discuss performance verification methodology appropriate for a variety of networks and applications.

“RF Passives on Silicon--The Intended and the Unintended” by Joachim N. Burghartz, sponsored by the IEEE Electron Devices Society In typical radio-frequency (RF) front-end circuits, the passive components outnumber the active devices. They occupy a major fraction of the total circuit area, and their low quality factor (Q) limits the circuit performance. Furthermore, these (intended) passive components can easily be perturbed by the interconnects feeding into them and coupled together by the (unintended) magnetic fields around those interconnects, or by (unintended) capacitive currents through the silicon substrate. One therefore needs to cope with both the optimization of the passive components, as far as Q and chip area consumption go, and the minimization of the crosstalk effects. This course illustrates the design principles that lead to optimized integrated passive components on the basis of maximum Q and optimum RF isolation. Taking the well-established hybrid RF systems on printed circuit board (PCB) as a reference, the most commonly used passive components are discussed, and RF isolation techniques at chip and package level are explained. After completing you should be able to develop an understanding of:

"Silicon-Germanium (SiGe) IC Devices & Technology" by John D. Cressler, sponsored by the IEEE Electron Devices Society The silicon-germanium heterojunction bipolar transistor (SiGe HBT) is the first practical bandgap-engineered device to be realized in silicon. SiGe HBT technology combines transistor performance competitive with III-V technologies such as GaAs and InP with the processing maturity, integration levels, yield, and hence cost commonly associated with conventional Si CMOS fabrication. Since the first demonstration of a functional transistor in 1987, SiGe HBT technology has emerged from the research laboratory, entered manufacturing on 200 mm wafers, and is currently making in-roads in the commercial electronics market in the US, Europe, and the Far East. First-generation SiGe HBTs can deliver: fT in excess of 50 GHz, fmax in excess of 70 GHz, minimum noise figure below 0.5 dB at 2.0 GHz, linearity efficiency (OIP3/Pdc) above 10, 1/f noise corner frequencies below 1 kHz, operation at cryogenic temperatures, excellent radiation hardness, as well as yield, reliability and cost comparable to Si. Aggressively-scaled SiGe HBTs are capable of achieving greater than 200 GHz transistor-level performance, and thus are expected to enable Si-based solutions for >40 GB/sec data links and emerging RF, microwave, and even mm-wave systems. A host of record-setting digital, analog, RF, and microwave circuits have been demonstrated using SiGe HBTs, and the combination of SiGe HBTs with advanced Si CMOS to form a SiGe HBT BiCMOS technology represents a unique opportunity for Si-based system-on-a-chip solutions for emerging wireless and wireline applications. This course will provide a comprehensive review of the state-of-the-art in SiGe HBTs and assess its potential for current and future wireless and wireline applications.

"Ultra-Wideband Radio Technology" by K. Siwiak, sponsored by the IEEE Communications Society Based on the book, "Ultra-wideband Radio Technology," Wiley: UK, 2004, Siwiak traces UWB technology through history, regulations, standards, system implementations and commercial applications. The course presents a judicious balance between sufficient technical detail for the seasoned practitioner, and practical and strategic observations to benefit technology managers, marketers and potential investors in the technology. The seasoned technologist will have enough technical content and references to gain a working introduction to the field, while the business professional can ignore the detail of equations but gains a knowledge of the business implications of UWB. UWB is legal in the USA, Japan, and by the ITU-R. A European Commission Decision mandates the introduction of UWB rules by member nations. Methods of generating and modulating UWB signals are described and set in the context of IEEE802 and other Standards. There has been a recent surge of invention and commercialization interest following the FCC's "Report and Order" which legalizes an unprecedented access to more than 7.5 GHz of unlicensed UWB spectrum in the US. Methods of generating and modulating UWB signals are described and set in the context of UWB proposals for IEEE802 Standards. Interesting UWB antenna, radiation, and propagation phenomena, including unique behavior in multipath, are presented in contrast with narrow band radio. Examples of UWB link margins including data throughput versus range and system data capacity (up to 2 Gb/s) are compared with conventional and much higher power 802.11a/b systems. The future of UWB is a judicious mix of wireless communications, precision positioning and radar. UWB can enable an accurate indoor adjunct to GPS with centimeter accuracy. Discussions of applications show that UWB capabilities make possible delivery of location-specific content and information, tracking of high value assets, security systems and various automotive and interesting home based "location awareness" systems. After completing this course you should be able to develop and understanding of:
