Abstract :
Direct all-digital frequency synthesizers are favored by modern nanoscale CMOS technologies but suffer from strong frequency spurs and timing irregularities. To counter these drawbacks various jitter-correction and spurs-suppression techniques have been proposed. This paper presents a comprehensive literature review and a comparative study of such techniques, applied to popular direct all-digital frequency synthesis cores, identifying their strengths and weaknesses.
