Abstract :
In this paper, we present a frequency synthesizer architecture and its simulation results. Frequency differences are detected digitally with a high speed counter. The oscillator output frequency is used as a clock signal for the digital blocks, whereas the output frequency accuracy can be traded off with the synthesizer settling time.
