Abstract :
A low-power monolithic clock synthesizer suitable for use in mobile μP platforms is presented. Clock synthesis is accomplished using an all-Si RF LC reference oscillator that does not require an external frequency reference. Fabricated in 0.18μm CMOS, the developed clock synthesizer demonstrates ±1% frequency accuracy over process, voltage, and 0-70°C, exhibits 7.4/21/33psrms period jitter on 528/66/50MHz clock signals, and achieves a start-up latency of only 3.2μs.
