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.
