Fractional-N frequency synthesizers that use a digital Δ-Σ modulator (DDSM) to control the feedback divider can exhibit spurious tones that move about in the frequency domain; these are known colloquially as ``walking'' or wandering spurs. Building

Apart from the well-known nonlinearity-induced fixed spurs, a DDSM divider-based fractional- $N$ frequency synthesizer can manifest spurs with time-varying frequency offsets from the carrier; these are called wandering spurs. This paper presents expe

A 4.48-GHz type-II charge pump fractional- ${N}$ PLL implemented in a 0.18- $\mu \text{m}$ BiCMOS process is presented. The divider controller’s output is processed using a novel block, the probability mass redistributor, which statistically reconf

The instantaneous divide value of the multimodulus divider in the feedback path of a fractional-N PLL is determined by a divider controller, which is usually implemented as a digital delta-sigma modulator $(\mathrm (D)\Delta \Sigma \mathrm (M))$. A d
