A low-power and high-SFDR Direct Digital Frequency Synthesizer based on adaptive recoding CORDIC

Direct Digital Frequency Synthesizer (DDS) plays an important role in communication systems. In this paper, we propose a novel DDS architecture. Compared with the conventional lookup table (LUT) based DDS, the proposed one adopts the coordinate rotation digital computer (CORDIC) algorithm to accomplish phase-to-amplitude conversion. Due to the poor accuracy… (More)
