Serpentine lines have been widely used in digital circuits to provide the required timing delays. Based on a full-wave simulation tool, some critical parameters that affect the delay characteristic of a serpentine line are carefully studied and analyzed. With the comprehensive study and analysis, a set of practical and useful design guides are concluded for designing a serpentine line to meet the...
In all modern high-speed digital board designs, every slightest discontinuity on the board has to be considered carefully, especially the vias, which are abundantly used in digital design. As frequency increases and signal rise time reduces, via causes impedance discontinuities resulting in signal reflections and hence deterioration of signal integrity (SI) and system performance. The paper carries...
