A Random-Based Fractional-N Frequency Divider for Spurious Tones Cancellation

Abstract : Abstract: A new fractional frequency divider is presented. It is based on a random dithering of the phase error. The divider output spectrum is cleaned from any fractional spurious tone. Moreover, as no noise shaping is applied, the proposed solution can be implemented in frequency synthesizers like Phase Locked Loops (PLL) without implication on the loop filter.
