5 Frequency synthesis(FS) is electronic system which generate periodic waveform.
The goal is to analyze and design FS in integrated circuit level. Most of designs are discussed in CMOS and rarely in BiCMOS and Bipolar(SiGe). FR also called Phase-lock-loop too(PLL).

7 Apllication Wireless application Data link application
Skew Cancellation Clock and Data Recovery

8 Frequency Synthesis (e.g. generating a 1 GHz
clock from a 100 MHz reference) • Skew Cancellation (e.g. phase-aligning an internal clock to the IO clock) (May use a DLL instead) • Extracting a clock from a random data stream (e.g. serial-link receiver)

12 Tuning Range muts be able to cover all channels
Purity of the output tone: Low phase noise or jitter Freedom from spurs Amplitude must be enough to drive mixers Step size should not be more than channel spacing

13 Settling time must be below a certain amount when channel is changed.
Acquisition time must be low enough to start FR very fast. I and Q Maching Power dissipation Synthesizer pulling(chirp) must low when other blocks turn on.
