High-speed arbitrary waveform generator based on FPGA

Abstract

With the development of electronic and information technology, the signal generator has been widely used in various fields of electronic technology. And the requirement of its performance is increasingly more and more superior, such as adjustable frequency and range, high frequency stability, fast conversion speed, etc. Meanwhile, Some uncommonly special waveforms are needed in some special environment, for example a waveform of 1/(T-t) form used in quantum random number generator. Therefore high-speed and stability arbitrary waveform generator have great significance for the practical application of scientific research. In this paper, the design of the arbitrary waveform generator is based on a FPGA chip: XC6SLX75T, using the DDS technology and a high-speed DAC, the digital sampling frequency is up to 1GHz.
