Interpolation-based digital quadrature frequency synthesizer
R. Larson, Shih‐Lien Lu · 2000
A novel quadrature sinusoid synthesizer is designed. This synthesizer is algorithmic in nature and requires no memory look-up table. Possible uses include conversion in RF based systems. This design is compared with a phase-accumulator based synthesizer and found to be optimal in area, transistor count, and spurious noise.
