Abstract

In this paper, an experimental circuit model for an accurate high-frequency characterization of transmission line is proposed. Inherent resonance effects during measurements make it difficult to determine characteristic impedance and propagation constant at the resonance frequencies corresponding to the line length. Thus, resonance-effect-free transmission line parameter determination technique based on the physical insight and theory is proposed. Then, by using the parameters high-frequency circuit model is proposed for high-speed signal propagation characterization. The proposed frequency-variant transmission line model is verified with measurement and it can be usefully exploited in high-speed signal propagation characterization.

본 논문에서는 전송선의 정확한 고주파 특성화를 위해 실험적 접근을 기반으로 한 회로모델을 제안한다. 측정 시 불가피하게 발생하는 공진현상으로 인하여 배선의 길이에 상응하는 공진주파수에서 특성 임피던스 및 전파상수를 정확히 결정하기 어렵다. 따라서 물리적 통찰 및 이론을 바탕으로 이러한 공진효과가 배제된 전송선 파라미터 결정 방법이 제시되었다. 또한 고속신호의 전파 특성화를 위해 실험적으로 결정된 파라미터를 사용한 고주파 회로모델이 제안되었다. 본 논문에서 제안한 주파수 종속 전송선 파라미터 모델은 측정을 통해 검증되었으며, 고속 신호의 전파 특성화에 유용하게 적용될 수 있다.
