Learn the techniques for designing and implementing anall-digital RF frequency synthesizer. In contrast to traditional RFtechniques, this innovative book sets forth digitally intensivedesign techniques that lead the way to the development of low-cost,low-power, and highly integrated circuits for RF functions in deepsubmicron CMOS processes. Furthermore, the authors demonstrate howthe architecture enables readers to integrate an RF front-end withthe digital back-end onto a single silicon die using standard ASICdesign flow.

Taking a bottom-up approach that progressively builds skills andknowledge, the book begins with an introduction to basic conceptsof frequency synthesis and then guides the reader through anall-digital RF frequency synthesizer design:

• Chapter 2 presents a digitally controlled oscillator (DCO),which is the foundation of a novel architecture, and introduces atime-domain model used for analysis and VHDL simulation
• Chapter 3 adds a hierarchical layer of arithmetic abstractionto the DCO that makes it easier to operate algorithmically
• Chapter 4 builds a phase correction mechanism around the DCOsuch that the system's frequency drift or wander performancematches that of the stable external frequency reference
• Chapter 5 presents an application of the all-digital RFsynthesizer
• Chapter 6 describes the behavioral modeling and simulationmethodology used in design

The final chapter presents the implementation of a fulltransmitter and experimental results. The novel ideas presentedhere have been implemented and proven in two high-volume,commercial single-chip radios developed at Texas Instruments:Bluetooth and GSM.

While the focus of the book is on RF frequency synthesizerdesign, the techniques can be applied to the design of otherdigitally assisted analog circuits as well. This book is amust-read for students and engineers who want to learn a newparadigm for RF frequency synthesis and wireless transmitter designusing digitally intensive design techniques.
