A low spurious level fractional-N frequency divider based on a DDS-like phase accumulation operation

Abstract

This paper presents a novel architecture of a low spurious level fractional-N frequency divider. It has already been shown in previous work that the use of a direct digital synthesizer (DDS) represents a promising solution to the mitigation of the fractional spurs that appear at the output of fractional frequency dividers, but with the drawback of causing a… (More)
