Abstract
A method and a phase-locked loop (PLL) for generating output clock signals with desired frequencies are described. The PLL is equipped with a ramp generator that increments or decrements a feedback divider value before providing it to a modulator. The modulator modulates the feedback divider value and provides the modulated value to a feedback divider of the PLL for performing frequency division.
