Abstract
A fractional N-frequency divider having a reduced fractional spurious output signal, which utilizes a multi-modulus frequency divider and an accumulator to generate a calibration-timing window that is used to calibrate two oscillator circuits and a phase compensation circuit. The calibrated phase compensation circuit is then used to mitigate the fractional spurs in the output signal of the fractional N-frequency divider. The fractional N-frequency divider may be implemented into a fractional N-frequency synthesizer.
