Abstract
Spectral purity of fractional-N frequency synthesisers is affected by a set of discrete spurious components. The paper investigates how the intermodulation effects in fractional-N frequency synthesizers contribute to these spurious components. The intermodulation mechanism has been investigated. The predictions of the distribution of intermodulation-born spurs are proven by a set of simulations. Potential approaches to suppress intermodulation-born spurs are also discussed.
