Abstract :
This paper presents a novel concept of using a phase-interpolation direct digital synthesizer for an Ultra Wideband MB-OFDM Alliance application as a low silicon area alternative to state of the art solutions. In particular, an investigation of the spurious tones in such direct digital synthesizer is presented and ways how to reduce their presence are discussed. The design and simulation of the critical blocks made using a 65-nm CMOS process are also presented.
