All-Digital Frequency Synthesizer in Deep-Submicron CMOS (PDF)

A new and innovative paradigm for RF frequency synthesis and
wireless transmitter design

Learn the techniques for designing and implementing an
all-digital RF frequency synthesizer. In contrast to traditional RF
techniques, this innovative book sets forth digitally intensive
design techniques that lead the way to the development of low-cost,
low-power, and highly integrated circuits for RF functions in deep
submicron CMOS processes. Furthermore, the authors demonstrate how
the architecture enables readers to integrate an RF front-end with
the digital back-end onto a single silicon die using standard ASIC
design flow.

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

* Chapter 2 presents a digitally controlled oscillator (DCO),
which is the foundation of a novel architecture, and introduces a
time-domain model used for analysis and VHDL simulation

* Chapter 3 adds a hierarchical layer of arithmetic abstraction
to the DCO that makes it easier to operate algorithmically

* Chapter 4 builds a phase correction mechanism around the DCO
such that the system's frequency drift or wander performance
matches that of the stable external frequency reference

* Chapter 5 presents an application of the all-digital RF
synthesizer

* Chapter 6 describes the behavioral modeling and simulation
methodology used in design

The final chapter presents the implementation of a full
transmitter and experimental results. The novel ideas presented
here 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 synthesizer
design, the techniques can be applied to the design of other
digitally assisted analog circuits as well. This book is a
must-read for students and engineers who want to learn a new
paradigm for RF frequency synthesis and wireless transmitter design
using digitally intensive design techniques.
