Direct Digital Frequency Synthesizer design using CORDIC algorithm

CORDIC 알고리즘을 이용한 DDFS 설계

This paper describes the architecture and the IC implementation of a Direct Digital Frequency Synthesizer (DDFS). That is based on an angle rotation algorithm (CORDIC). It is shown that the architecture can be implemented as a multipliers, feedfoward, and easily pipelineable datapath. A prototype IC has been designed, fabricated in 0.35${\mu}{\textrm}{m}$ SAMSUNG KG90 Library.
