Abstract

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 Â¿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.
