摘要：
In this paper, a high-speed direct digital frequency synthesizer digital circuit design is presented, which integrates phase accumulator, phase offset producer, sine/cosine mapping function, amplitude modulator, clock generator. The DDFS is processed in 0.18 mu m TSMC CMOS technology. The verification results show that the DDFS capable of handling frequency, phase, amplitude modulation and generating high-speed agile sine/cosine waveform.(1)
