I got a problem when I read some paper about delta-sigma modulator in fractional-N synthesizer.
For my understanding, the input range of DSM is 0~1, because normally, N= M+k/2^K.But in some papers, it mentioned input stable range covers from 0.5 to 1.5 ( Keliu Shu, a comparative study of digital delta-sigma modulators for fractional-N synthesizer) and other input range in other papers.
Anybody can give me some explaintion about that ?
Thanks
