Abstract :
This paper presents a new PLL architecture that provides a larger frequency band of phase noise filtering in order to relax VCO building constraints. It consists in a classical PLL with a parallel band pass loop. This topology is called composite PLL. This paper presents some behavioral simulation of such PLL
