Abstract :
An efficient quadraphase generation algorithm and associated hardware implementation for the creation of phase-modulated waveforms are presented. They result in spurious performance that is limited only by available digital-to-analog converter (DAC) widths. This architecture yields an efficient implementation of a direct digital synthesizer. The design technique and associated performance characterizations are applied to designs that require increased resolution
