A 1.8-Ghz CMOS Fractional -N Frequency Synthesizer With Randomized Multiphase VCO

92 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2003.To demonstrate the concept, a fully integrated 1.8-GHz frequency synthesizer with randomized multiphase VCO was designed. The prototype, implemented in a standard 0.6-mum CMOS technology, achieves -118 dBc/Hz phase noise at 1-MHz offset and exhibits close-in phase noise between -80 and -90 dBc/Hz up to the PLL loop bandwidth. The synthesizer has a frequency resolution of 10 Hz and dissipates 52 mW from a 3.3-V supply.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
