Spread Spectrum Clock Generator With Adaptive Band

本研究提出一种新颖的数位至时间转换器机制，用于产生展频时脉。提出的方法可用于扩展频谱时钟产生的高级形式，也可用于电力电路切换电磁干扰的减少和定制。 建立在所提出的算法是一个自动配置的EMI排除。这使得限制EMI噪声的产生与周围的电路在电路利用的时间，而不是在设计stages. Experimental结果，我们的FPGA实现，已经表明，没有妥协的电路功能的能力，我们提出的方法可以获得-38到-100[dB]的噪声阻碍在选择性频段。

This research has proposed a novel Digital-To-Time Converter mechanism for use in spread-spectrum clock generation. By this, certain spectrum bands can be excluded from spreading spectrum.Proposed methods are utilizable in advanced form of spread spectrum clock generation and also applicable to power circuits switching electromagnetic interference reduction & customization. Built upon proposed algorithms was an auto-configurable EMI exclusion. This enables limiting EMI noise generation with regards to surrounding circuits at the time of circuit utilization rather than the design stage.Experiment results on our FPGA implementation, have shown with no compromise on circuits functioning capabilities, our proposed methods can obtain -38 to -100[dB] noise hampering in selective bands.
