A new mechanism producing discrete spurious components in fractional-N frequency synthesizers
Fractional-N frequency synthesis is a powerful technique for generating the pure signals with agile tuning needed in modern mobile communications systems, particularly mobile base-stations. This paper describes a new mechanism discovered by the principal author that sets a fundamental limit on the spurious performance of fractional-N frequency synthesisers and thus helps to better understand and design these important subsystems. This work was initially funded by Nokia (Ian Thompson, £49,500) and subsequently by EPSRC (EP/D05012X/1, £213,436, PI: Brennan) and the results described in this paper have been acknowledged by the world’s most eminent expert in this field, Dr Floyd Gardner (California).
