The allocation of frequency spectrum by the FCC for Ultra Wideband (UWB) communications in the 3.1-10.6 GHz has paved the path for very high data rate Gb/s wireless communications. Frequency synthesis in these communication systems involves great challenges such as high frequency and wideband operation in addition to stringent requirements on frequency hopping time and coexistence with other wireless standards. This research proposes frequency generation schemes for such radio systems and their integrated implementations in silicon based technologies. Special emphasis is placed on efficient frequency planning and other system level considerations for building compact and practical systems for carrier frequency generation in an integrated UWB radio. This work proposes a frequency band plan for multiband OFDM based UWB radios in the 3.1-10.6 GHz range. Based on this frequency plan, two 11-band frequency synthesizers are designed, implemented and tested making them one of the first frequency synthesizers for UWB covering 78% of the licensed spectrum. The circuits are implemented in 0.25[mu]m SiGe BiCMOS and the architectures are based on a single VCO at a fixed frequency followed by an array of dividers, multiplexers and single sideband (SSB) mixers to generate the 11 required bands in quadrature with fast hopping in much less than 9.5 ns. One of the synthesizers is integrated and tested as part of a 3-10 GHz packaged receiver. It draws 80 mA current from a 2.5 V supply and occupies an area of 2.25 mm2. Finally, an architecture for a UWB synthesizer is proposed that is based on a single multiband quadrature VCO, a programmable integer divider with 50% duty cycle and a single sideband mixer. A frequency band plan is proposed that greatly relaxes the tuning range requirement of the multiband VCO and leads to a very digitally intensive architecture for wideband frequency synthesis suitable for implementation in deep submicron CMOS processes. A design in 130nm CMOS occupies less than 1 mm2 while consuming 90 mW. This architecture provides an efficient solution in terms of area and power consumption with very low complexity.

The increasingly demanding performance requirements of communications systems, as well as problems posed by the continued scaling of silicon technology, present numerous challenges for the design of frequency synthesizers in modern transceivers. This book contains everything you need to know for the efficient design of frequency synthesizers for today's communications applications. If you need to optimize performance and minimize design time, you will find this book invaluable. Using an intuitive yet rigorous approach, the authors describe simple analytical methods for the design of phase locked loop (PLL) frequency synthesizers using scaled silicon CMOS and bipolar technologies. The entire design process, from system-level specification to layout, is covered comprehensively. Practical design examples are included, and implementation issues are addressed. A key problem-solving resource for practitioners in IC design, the book will also be of interest to researchers and graduate students in electrical engineering.

A frequency synthesizer plays a critical role in defining the performance of wireless systems in terms of measures such as operating frequency range, settling time, phase noise and spur performance, and area/power consumption. As the trend in mobile system design has changed from single-standard systems to multi-standard/multi-application systems, the role of frequency synthesizers has become even more important. : As the most popular architecture, a phase-locked loop (PLL)-based frequency synthesizer has been researched over the last several decades; however, many unsolved problems related to the PLL-based synthesizer are still waiting for answers. This dissertation addresses key challenges related to fully integrated PLL-based frequency synthesizers, including the problem of large area consumption of passive components, the inherent reference-spur problem, and the problem of trade-offs between integer-N PLLs and fractional-N PLLs.

This work is aimed at practitioners wishing to gain a broader systems-based perspective of phase-locked loops; and is also suitable as a graduate text for engineering students. It provides detailed coverage of digital sampling effects in modern phase-locked frequency synthesizers from a systems perspective, and discusses all aspects of phase noise, its mathematical modelling and its impact upon different digital communication systems. Sections on building blocks for frequency synthesis using phase-locked loops, frequency synthesis using sampled-data control systems, and MASCET, are included.

The landmark text on frequency synthesizers-now in paperback Frequency Synthesizers: Theory and Design, Third Edition is the newest edition of Vadim Manassewitsch's definitive treatment of the subject. Updated to include the latest achievements in the performance of crystal-controlled oscillators, the design theory of fast-switching-time synthesizers, and an example of their practical applications, the book continues to be a complete guide for everyone who works with synthesizers. Intended to formulate basic design principles and to demonstrate design procedures meeting several stringent requirements simultaneously, its emphasis is on high-speed synthesis and its new applications in radar, spread spectrum communications, automatic test equipment, and nuclear magnetic resources. Manassewitsch describes numerous approaches to ultra-stable signal sources generating spectrally pure signals of high accuracy, and shows how various building blocks such as mixers, oscillators, and frequency multipliers and dividers are used in frequency synthesis. To meet the needs of engineers in this rapidly growing field, Manassewitsch has added several novel frequency synthesis techniques, developed the principles of high-speed synthesis, and described new synthesizers using important design approaches. A summary of the most recent developments in frequency generation and control, the book is firmly based on the realities of current design practices in the United States as well as abroad. With an intermodulation products chart among its figures, a computer program that calculates the frequencies of mixer intermodulation products among its appendices, and a bibliography of more than 190 references, Frequency Synthesizers: Theory and Design continues to be an invaluable aid for engineers, managers, instructors, and students.
