提出一种基于双DDS芯片技术的锯齿波发生器的设计,讨论了DDS器件在技术实现中的具体应用,解决了传统锯齿波信号发生器输出频率精度差、频率改变不够灵活等缺点.该波形发生器具有输出频率稳定,准确、波形质量好和输出频率范围宽等优点.经仿真和实验验证了该方案的可行性.

This paper presents a design of saw-tooth waveform generator which is based on double DDS Chip. It mainly introduces the application of DDS technology in the design. Compared with traditional methods of the saw-tooth waveform generator, the method has lots of advantages. For example, the frequency is digitally programmable, and the design requires no external components to change the frequency. The frequency does not change with component drift over time or temperature.
