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).
Apllication • Wireless application • Data link application • Skew Cancellation • Clock and Data Recovery
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)
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
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.
Optical System=10Gb/s • High pass corner frequency =250KHz • What is the longest run befor 0.2dB
