Abstract
This work presents a general architecture for all-digital frequency synthesizers based on a frequency-shifted Σ/Δ modulator. The synthesizers can achieve spurs free spectrum within the band of interest and high dynamic range. System level aspects of the synthesizers are discussed and MATLAB simulation results are presented.
