Modeling of fractional-N division frequency synthesizers with SIMULINK and MATLAB

Presents a set of SIMULINK models and MATLAB files, which allow exhaustive behavioral simulations of fractional-N division frequency synthesizers based on PLL. The proposed set of models takes into account most of PLL's non-idealities. For each model we present a description of the considered effect as well as all of the implementable details. Simulation results on a fractional-N division frequency synthesizer based on PLL demonstrate the validity of the models proposed.
