Abstract :
Based on the flying-adder structure, an all-digital frequency synthesizer with dual resolutions is designed and implemented. The range of the output frequencies of the all-digital frequency synthesizer is analyzed. The devised frequency synthesizer with dual resolutions is realized using the UMC 0.18- mum cell-based CMOS process. Corresponding simulation results and realization performance are presented.
