  3. Abstract:
  4. This paper presents a new architecture for a DLL based frequency synthesizer for wireless transceivers. Owing to its DLL based nature, the synthesizer generates the target frequencies with minimum phase noise and jitter. To cover the desired frequency proposed architecture consists of mixer and divider. As an example, VHF frequency band of IRAN is covered. The circuit level design guidelines and power consumption trade-offs are presented. It was shown that for the mentioned standard a 40 delay cell and 9 switches for switching channels is sufficient. Simulation results confirm the analytical predictions
