Abstract :
In this paper, we propose all-digital frequency synthesizer architecture, based on an all-digital SigmaDelta-frequency discriminator. The new all-digital synthesizer is compared to previously published work. The architecture of the SigmaDelta-frequency discriminator is verified using behavioral simulation
