  3. Abstract:
  4. This paper presents a new architecture for a DLL based frequency synthesizer. Occupying low area, lower power consumption and phase noise are the advantages of this novel architecture. DLLs are first ordered systems, so good stability can be obtained in this design. This structure also can be used for generating fractional multiple of reference frequencies. The proposed circuit can operate at a substantially low supply voltage. A case in point, the synthesizer is adopted to create the channel frequencies of French DVB-H/T standard. The circuit is designed based on 0.13um CMOS Technology. Also power consumption trade-offs are introduced. It was shown that 27 delay cells are sufficient to cover the mentioned standard. Simulation results confirm the analytical predictions
