Chapter 10. Integer-N Frequency Synthesizers

The oscillators used in RF transceivers are usually embedded in a “synthesizer” environment so as to precisely define their output frequency. Synthesizer design has for decades proved a difficult task, leading to hundreds of RF synthesis techniques. RF synthesizers typically employ phase-locking and must deal with the generic PLL issues described in Chapter 9. In this chapter, we study one class called “integer-N” synthesizers. The chapter outline is shown below. The reader is encouraged to first review Chapters 8 and 9.
