Abstract

A novel technique to suppress quantisation noise in a fractional-N phase-locked loop (PLL) using a fine-resolution multi-element fractional divider is presented. The proposed technique suppresses noise uniformly over the entire frequency range. It is mostly digital and is applicable for both analogue and digital PLLs. The proposed technique with an eight-element fractional divider can suppress the quantisation noise by 18 dB compared with a conventional fractional-N PLL.
