Patent ID: 7532049

Claim:
A reduced-noise frequency divider system (“RNFDS”), comprising: a frequency divider configured to receive an input signal and, in response, to produce a divided signal; and a resampler connected to receive the input signal and the divided signal, and operable in response to the input signal to resample the divided signal to produce a resampled output signal; wherein: the RNFDS additionally comprises a delay module connected to receive the divided signal and operable to produce a delayed divided signal; and the resampler comprises: a first resampler connected to receive the divided signal and an antiphase component of the input signal and operable in response to the antiphase component of the input signal to resample the divided signal to produce a first resampled signal component, a second resampler connected to receive the delayed divided signal and an in-phase component of the input signal and operable in response to the in-phase component of the input signal to resample the delayed divided signal to produce a second resampled signal component, and a summing node at which the resampled signal components are summed to produce the resampled output signal.
