Study of Meander Line Delay in Circuit Boards

Barry J. Rubin, Member, IEEE and Bhupindra Singh

Page 1452.

Abstract:

A moment technique is used to determine the propagation delay in meander (serpentine) delay lines located in printed circuit boards of computer systems. The full three-dimensional effects of the meander structure including signal line thickness, right-angle bends, and skin-effect are included. A set of delay lines having different pitches are considered, and results are calculated and compared to those from two-dimensional simulations, other commercial codes, analytic formulas in the literature, and experimental measurements. Based on the consistency of the results and sensitivity analyses involving numerical gridding and frequency content, the delays calculated for meander lines situated in a homogeneous medium are accurate to better than a few tenths of a percent.
