Techniques for In-Band Phase Noise Reduction in Δ Σ Synthesizers.

Evaluates several techniques used to reduce the in-band phase noise contribution of ΔΣ (DS) fractional-N frequency synthesizers and develops several practical techniques for specifying the noise and linearity of components used in a DS fractional-N frequency synthesizers, as of November 2003. Highlights of such synthesizers used in this evaluation; Suitability of these synthesizers for resolving problems faced by radio system designers; Sources of in-band noise; Overview of the integrated circuit design used in this evaluation.
