  • Patent number: 10879916
    Abstract: Techniques are described for implementing fractional dividers in modulated phase-lock loop circuits. For example, a fractional divider can receive a base dividing value having integer and fractional components (e.g., corresponding to a carrier frequency produced by multiplying the dividing value by a reference frequency). The fractional divider can also receive a data signal to modulate the dividing value. Embodiments use a shift value (e.g., preset, or received via a shift input signal) to selectively shift and scale the modulated dividing value to generate a shifted fractional component value. The shifted fractional component value can be added to the base integer component, and de-shifted and de-scaled to generate a corrected dividing value. A feedback signal can then be generated by sequentially dividing a frequency of a clock output signal by the corrected dividing value.
