Efficient and accurate signal transient and crosstalk noise determination of frequency-variant RLC transmission lines

A new signal transient and crosstalk noise determination method of frequency-variant RLC transmission lines is presented. In order to investigate the realistic transmission line characteristics, two coupled lines are experimentally characterized by using s-parameters up to 20GHz. Then the signal transients and crosstalk noises are directly determined with the measured s-parameters and compared with conventional SPICE simulation results. Thereby, it is shown that the conventional approach may lead to significant design error. In contrast, the proposed method is very accurate as well as efficient.
