This Letter presents a method of predicting the phase noise limits of static frequency dividers. The proposed phase noise model for free-running and injection-locked modes is based on the circuit parameters only. The model provides an intuitive comprehension of the phase noise behaviour of static frequency dividers and is proved to be useful in primary hand calculations. The method was verified against measurement results of a static frequency divider-by-two, operated at 77 GHz and fabricated in a SiGe process.
