Abstract:
A fractional-N frequency synthesizer comprising a multi-phase generator, a multi-path error phase generator; a current combiner; a loop filter connected to the current combiner; an oscillator (150) connected to the loop filter; a frequency divider (160); a SDM connected to both the frequency divider and the multi-phase generator, to generate variable division ratio.
