Abstract :
All-digital frequency synthesizers are favored by modern nano-scale CMOS technologies but suffer from strong frequency spurs and timing irregularities. This paper reviews the time-domain-correction and spurs-suppression techniques for all-digital frequency synthesizers, identifies their strengths and weaknesses and provides new research directions.
