Download or read book CMOS Fractional-N Synthesizers written by Bram De Muer and published by Springer Science & Business Media. This book was released on 2003-01-31 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines the design of monolithic CMOS frequency synthesizers that can attain the highest spectral purity and fast switching with moderate power consumption, namely a DS-controlled fractional-N synthesizer. The authors (KU Leuven) first review the requirements of the frequency synthesizer in the DCS-1800 system, then develop high speed frequency dividers, high speed voltage controlled oscillators (VCOs), and a dual-path phase-locked loop (PLL) filter. The final chapter presents a monolithic 1.8 GHz DS fractional-N PLL frequency synthesizer, which may lead to an inexpensive cellular transceiver solution.
