Book Description
As CMOS technology continues to advance to smaller feature sizes, digital-logic circuits use less power while becoming faster and smaller. On the other hand, wireless analog circuits often benefit from the higher speed, but suffer various ill effects making conventional analog circuits difficult to design. Integrating wireless analog functionality onto high-volume CMOS greatly reduces the size and cost of wireless devices, which is motivating a tsunami of engineering innovation. In this work we present three wireless analog functions in CMOS: a linearized varactor, phased-locked loop (PLL), and power-amplifier (PA}. To improve the tuning linearity at the cost of a lower capacitance tuning ratio, many circuits tune a large varactor over a small portion of its tuning range. We demonstrate here that a conventional varactor's performance can be improved by breaking it into smaller, independently tuned, parallel segments. This increased tuning dimensionality can enable a varactor to be realized with a high tuning linearity over most of its tuning range while reducing the capacitance's dependence on the instantaneous radio-frequency input signal. In many applications, PLLs need to have a large fine-tuning frequency range to accommodate environmental drift such as temperature. Typically, the fine-tuning sensitivity of the varactor in a PLL's voltage-controlled oscillator is proportional to its fine-tuning range, which makes the PLL more susceptible to picking up noise and spurs. A new dual-path PLL architecture is introduced that uses a softly switched varactor array in a digitally controlled integral path. This architecture decouples the PLL's tuning sensitivity from its tuning range, thus achieving a very low fine-tuning sensitivity. To realize high spectral efficiency, many wireless schemes modulate both the radio-frequency carrier's phase and envelope, necessitating the use of a linear PA. Hence battery powered wireless transceivers require a PA that is both linear and power efficient, which, over even a modest dynamic range, would be difficult to implement in CMOS. Various PA linearization methods are discussed leading to the chosen polar-feedback method. The designs, implementations and measurements for some key blocks required for a PA with polar feedback are presented and the challenges remaining to implement a working system are discussed.

Book Description
Over the past decade, great strides have been made in the technology of microwave oscillators and synthesizers, with digital frequency synthesizers in particular attracting much attention. These synthesizers are now being used in virtually all modern signal generators and radio communication equipment. Until now, however, detailed information about their design has been hard to come by-much of it scattered through journal articles-and most books on the subject have taken a primarily theoretical approach. Enter Microwave and Wireless Synthesizers-the first book to emphasize both practical circuit information from RF to millimeter-wave frequencies and up-to-date theory. Based on course material taught by author Ulrich L. Rohde at George Washington University and recent work done by the author at Compact Software, Inc. and Synergy Microwave Corporation, this volume is a complete revision and update of Rohde's landmark text, Digital PLL Frequency Synthesizers: Theory and Design. While it provides all the necessary theory and formulas, it also offers an in-depth look at the practical side of the phase-lock loop (PLL) in synthesizers-including special loops, loop components, and practical circuits-material that is not available in any other book. Rohde explains loop fundamentals, demonstrates the linear approach to oscillator phase noise, discusses the digital direct synthesizer technique, addresses low noise oscillator design, and provides insight into the role and design of crystal oscillators, mixers, phase/frequency discriminators, wideband high-gain amplifiers, programmable dividers, and loop filters. He goes on to cover conventional multiloop synthesizers and survey existing state-of-the-art microwave synthesizer applications. Extensive appendices review the mathematics of useful functions and various applications, including even the complex nonlinear theory of noise in large signal systems such as mixers and oscillators. Microwave and Wireless Synthesizers allows anyone with a PC running either Windows 3.11 or Windows NT to explore real-world design. It uses programs for the solution of digital phase-lock loop systems, tabulates the results, and shows how Bode diagrams are determined by the computer's graphic capabilities. It also includes examples using commercially available linear and nonlinear CAD programs to provide accurate evaluation and optimization of oscillators and other useful circuits and many practical charts. For companies involved in test and communication equipment, this book reduces design and research costs by providing a large number of proven circuits and expediting the design process. It is also an outstanding senior/graduate level textbook for electrical engineering students and an invaluable resource for practicing engineers, senior engineers, and managers who would like to be able to evaluate new trends and techniques in the field.

Book Description
This book describes the design and implementation of an electronic subsystem called the frequency synthesizer, which is a very important building block for any wireless transceiver. The discussion includes several new techniques for the design of such a subsystem which include the usage modes of the wireless device, including its support for several leading-edge wireless standards. This new perspective for designing such a demanding subsystem is based on the fact that optimizing the performance of a complete system is not always achieved by optimizing the performance of its building blocks separately. This book provides “hands-on” examples of this sort of co-design of optimized subsystems, which can make the vision of an always-best-connected scenario a reality.
