description

Methods to simplify digital frequency synthesizers based on the co-ordinate rotation digital computer (CORDIC) algorithm are presented. Application of these methods leads to performance enhancement, compared with the topologies previously proposed in the literature. For a given output precision, hardware resources are reduced and spur-free dynamic range is increased.
