摘要：

This paper describes a delta-sigma (DELTA-SIGMA) modulation and fractional-N frequency division technique to perform indirect digital frequency synthesis based on the use of a phase-locked loop (PLL). The use of DELTA-SIGMA modulation concepts results in a beneficial noise shaping of the phase noise (jitter) introduced by fractional-N division. The technique has the potential to provide low phase noise, fast setting time, and reduced impact of spurious frequencies when compared with existing fractional-N PLL techniques.
