Direct Digital Synthesizer Design

A project for ECE 547 "VLSI Design" - Spring Semester 2006
Department of Electrical and Computer Engineering
University of Maine

Designed by: DESIGNER

My Direct Digital Synthesizer IC design has been created and submitted for fabrication on a 1.5mm x 1.5mm silicon chip. This project meets requirements of ECE547 VLSI Design / Layout class where I have performed my own CMOS transistor level design, simulation, partial custom chip layout, complete verification, and parasitic extraction.

A Direct Digital Synthesizer (DDS) produces an analog waveform – usually a sine wave – by generating a time-varying signal in digital form and then performing a digital-to-analog conversion. Because operations within a DDS are primarily digital, it can offer fast switching between output frequencies, fine frequency resolution and operation over a broad spectrum of frequencies.
