Digital synthesizers and transmitters for software radio
By programming the digital synthesizers and transmitters, adaptive channel bandwidths, modulation formats, frequency hopping and data rates are easily achieved. Techniques such as digital predistortion for power amplifier linearization, digital compensation methods for analog I/Q modulator nonlinearities and digital power control and ramping are presented in this book
CMOS single chip fast frequency hopping synthesizers for Wireless multi-gigahertz applications : Design methodology, analysis, and implementation
Describes an efficient design and characterization methodology that has been developed to study loop trade-offs in both open and close loop modelling techniques. This is based on a simulation platform that incorporates both behavioral models and measured/simulated sub-blocks of the chosen frequency synthesizer. The platform predicts accurately the phase noise, spurious and switching performance of the final design. Therefore excellent phase noise and spurious performance can be achieved while meeting all the specified requirements. The design methodology reduces the need for silicon re-spin enabling circuit designers to directly meet cost, performance and schedule milestones. The developed knowledge and techniques have been used in the successful design and implementation of two high speed multi-mode fractional-N frequency synthesizers for the IEEE 801.11a/b/g standards. Both synthesizer designs are described in details.
CMOS PLL synthesizers : Analysis and design
CMOS PLL Synthesizers: Analysis and Design presents both fundamentals and state-of-the-art PLL synthesizer design and analysis techniques. A complete overview of both system-level and circuit-level design and analysis is given. A 16mW, 2.4GHz, sub-2V, S D fractional-N synthesizer prototype is implemented in 0.35mm CMOS. It features a high-speed and robust phase-switching prescaler, and a low-complexity and area-efficient loop capacitance multiplier, which tackle speed and integration bottlenecks of PLL synthesizers." "This book is useful as a PLL synthesizer manual for both academic researchers and industry design engineers.
