  • Abstract
    Recent trends in the commercial use of fractional-N frequency synthesis can be attributed to the characteristic of independent loop bandwidth-channel spacing that results in low phase noise and relaxes the phase-locked loop (PLL) design constraints. This paper reviews several techniques used to implement fractional-N frequency synthesizers and discusses the advantages and disadvantages. It also addresses design options and associated trade-offs.
