Summary:
Digital-signals propagating in the PCB traces are being distorted seriously causing system failures as the clockfrequency increases. And it is getting difficult to improve the distortions with conventional impedance-matching technique as the clock frequency increases to GHz, which is called "Signal- Integrity (SI) problem in the GHz era". In order to overcome this problem, we have already proposed a novel PCB-trace structure called "Segmental Transmission Line (STL)", which is designed using the genetic algorithms. In this paper, we develop a 250MHz-scale-up prototype of the STL and show effectiveness of the STL by measuring the signals propagating in the prototype.
