"Applications of Neural Networks for RF Design" by Q.J. Zhang and K.C. Gupta, sponsored by the IEEE Microwave Theory and Techniques Society Neural Networks are information processing systems inspired by the ability of human brain to learn from observations and to generalize by abstraction. It has been used in diverse fields such as pattern recognition, speech processing, control, medical applications and more. In recent years, it has emerged as an attractive vehicle in the RF/microwave CAD community to address the challenges in high-frequency electronic modeling and design. Neural networks can learn and generalize from data allowing model development even when component formulas are unavailable. Neural network models are universal approximators allowing re-use of the same modeling technology for both linear and nonlinear problems and at both device and circuit levels. This course will include introductions, modeling and optimization for design, neural network structures and training, applications to passive and active component modeling, applications to linear and nonlinear circuit optimization including filter and amplifier examples, and knowledge based approach enhancing existing RF/microwave models through neural networks. After completing this course you should be able to develop an understanding of:

"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:

Coming 2Q 2009: “Highly Integrated, Re-Configurable RF Receiver Front-Ends in Deep Sub-Micron CMOS” by Naveen Yanduru, sponsored by the IEEE Microwave Theory and Techniques Society Various RF bands, standards, modulation schemes, duplex mechanisms and signal bandwidths needed for the mobile terminal call for a highly adaptable and reconfigurable RF receiver. The biggest bottleneck in achieving this goal lies with the RF pre-select filter at the antenna, which is band specific and creates a bottleneck in being able to share the hardware. Solving this “multi-band” programmability is the biggest challenge in achieving a RF Receiver for software defined radio. A few of the possible architectures and their limitations are presented. However, designing a “multi-mode” RF receiver for a given RF band with highly reconfigurable performance is an achievable goal. A WCDMA/EDGE receiver without inter-stage SAW filter in 90nm digital CMOS is used as an example in illustrating the architecture, circuit and system considerations for such a receiver.

Coming 3Q 2009: “Performance Requirements and Verification of the IEEE 802 Wireless Technologies” by Fanny Mlinarsky, sponsored by the IEEE Educational Activities Board The 802.11 market has seen spectacular growth over the past few years, and this growth is continuing at unprecedented rates. 802.11 technology has had a profound impact on the way consumers work, and on their leisure activities. Growing from cottage industry to a mainstream market across multiple segments, 802.11 products have become increasingly sophisticated; moving beyond traditional internet connectivity to include phones, cameras, gaming systems and even televisions. As 802.11 technology has advanced and the industry has matured, the testing methodologies continue to advance as well. Early testing methodologies primarily focused on whether or not two products could exchange data and seamlessly interoperate. 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.
