Abstract

This paper presents a new fractional frequency synthesizerarchitecture and its semi-global stability and robustness analysistool. The proposed analysis tool takes into account the switchedand non linear characteristics of the system components. In orderto validate this study, simulation results were obtained withelectronics simulators.
