Configuring the phase accumulator for frequency synthesization
R. Seshasayanan, Govindaswamy Indhumathi · 2016
The main objective of this paper is to create a novel approach for synthesizing multi-channel sine wave and square wave. In several kinds of equipment, it is essential to produce the accurate waveforms under various frequencies and profiles such as agile frequency source. Also it should have low phase noise, low spurious signal content for communication in various applications. Direct Digital Synthesizer [DDS] can provide more significant advantages using the PLL approaches such as continuous phase switching response, fine tuning the frequency resolution, settling time speedily, and reducing the noise. These are the features which help to obtain a good DDS system. The main motto of this paper is to describe about a DDS circuit structure and design a better DDS in detail.
