Textbook in PDF format The organization of the book is as follows: In Chapter 1 we give necessary background by introducing basic concepts of frequency synthesis and its possible realizations in a modern wireless transceiver. In Chapter 2, the frequency synthesizer design starts with a raw digitally controlled oscillator (DCO), which is the foundation of a novel digital architecture. A time-domain model, which is used extensively for analysis and VHDL simulation, is introduced. In Chapter 3, a hierarchical layer of arithmetic abstraction is added over the DCO which makes it easier to operate algorithmically. The main task of this overlay block is to perform DCO calibration and normalization such that the normalized DCO transfer function is largely independent of the process and environmental factors. Other improvements, such as increasing the frequency resolution through SD dithering and dynamic element matching, are also introduced. In Chapter 4, a phase correction mechanism is built around the normalized DCO oscillator such that the frequency drift or wander performance of the system is as good as that of the stable external frequency reference. In Chapter 5, an application of the all-digital RF synthesizer is presented. A frequency modulation capability is added to the synthesizer core to enable it to perform transmitter data modulation efficiently. A full transmitter is completed with the addition of two blocks. The first of these blocks is the transmitter pulse filter operating in baseband. The second block is a class E power amplifier that is capable of emitting an RF signal with a power level of several milliwatts. In Chapter 6, the behavioral modeling and simulation methodology used in the design are described. Finally, the implementation details of a full transmitter and experimental results are presented in Chapter 7
