On ΔΣ fractional-n frequency synthesizers
ΔΣ fractional-N frequency synthesis achieves low phase noise performance while relaxing the Phase-Locked Loop (PLL) design constraints and reduces the desired channel spacing. This paper reviews the recent advanced techniques on the implementation of fractional-N frequency synthesizers and discusses their advantages and disadvantages. It also addresses the design options and the associated trade-offs.
