Digital Frequency Synthesizer

This paper presents a novel algorithm and architecture for digital frequency synthesis DFS . It is based on a simple difference equation. Simulation results show that the proposed DFS algorithm is preferable to the conventional phase-locked-loop frequency synthesizer and the direct digital frequency synthesizer in terms of the spurious-free dynamic range SFDR and the peak-signalto-noise ratio P...

A wideband digital frequency synthesizer

I I I I / With the rapid advance in CMOS technology. the trend.of the VLSI then towards system-on-chip (SOC) where design methodology. cost. and turnaround time are major issues. Concepts of intellectual property (IP) are then proposed to fit for SOC designs. Based on a DFS controller IP [4]. a wideband digital frequency synthesizer (DFS) is proposed to fit in with the wireless LAN applications...

An Introduction to the SSSP Digital Synthesizer

l One of the main interests of the Structured Sound Synthesis Project (SSSP) is to develop a highly interactive environment to serveas an aid in the composition of music. We would like to do this within the context of a small, inexpensive, accessiblesystem. In order to resolve the conflict between the high computational demands of sound synthesis and these design objectives, we have developed a...

Pentomics Patents: Direct Digital Frequency Synthesizer

Direct Digital Frequency Synthesizer Pentomics’ first DDS patent concerns a method and apparatus for DDS which, unlike the traditional table-lookup methods, uses a simplified “angle-rotation” algorithm implemented as a multiplierless feedforward datapath, allowing easy pipelining and limiting the accumulation of roundoff errors. Our DDS’s modular architecture permits outputs of arbitrary precis...

An optimized Direct Digital Frequency Synthesizer (DDFS)

An optimized Direct Digital Frequency Synthesizer (DDFS) design in terms of reduced ROM, high throughput and speed is designed in this paper. DDFS is designed with 200 MHz reference clock frequency and 32 bit FTW for the generation of sine and cosine signal with 16 bit output frequency having frequency resolution of 0.0466 Hz and Phase resolution of 0.0055°. DDFS design is simulated using VHDL ...
