Abstract
An oscillator provides a plurality of clock signals, including a first clock signal having a first frequency and a first period, wherein each clock signal has the first frequency and is phase shifted from the first clock signal by an integer times a predetermined fractional amount of the first period. A multiphase frequency divider receives the plurality of clock signals and provides a divided clock output, and includes an integer frequency divider which provides the divided clock output based on a modified clock input and a clock selector which provides a current clock as the modified clock input during a first portion of the divided clock output and a next clock as the modified clock input during a subsequent portion of the divided clock output. The next clock is selected from the plurality of clock signals based on a selected fractional phase shift amount indicated by a sigma-delta modulator.
