• 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 GHzclock from a 100 MHz reference)• Skew Cancellation (e.g. phase-aligning an internalclock to the IO clock) (May use a DLL instead)• Extracting a clock from a random data stream(e.g. serial-link receiver)

ی

• 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.

Data Link Application

Intersymbol interference

High Pass filtering and DC wandering

• Optical System=10Gb/s• High pass corner frequency =250KHz• What is the longest run befor 0.2dB
