Abstract

트위스티드-페어 도체 라인 구조는 절연 도전 충돌(31,32)을 갖는 기판(22)위에 형성된다. 도전 층들은 제1, 제2, 제3 및 제4 도전성 플래나 세그먼트들(40,41,42,43)을 형성하는데 사용된다. 제1 도전성 링크(44)는 제1 신호 경로를 제공하기 위해 제1 및 제2 플래나 도전성 세그먼트들을 결합시킨다. 유사하게, 제2 도전성 링크(46)는 제2 신호 경로를 제공하기 위해 제3 및 제4 플래나 도전성 세그먼트들을 결합시킨다. 제1 및 제2 신호 경로들에서 트위스트(17)를 형성하기 위해 동작상 정렬되어서, 트위스티드 도전성 세그먼트들 주위의 최종 자기장들(57,59)이 서로 상쇄되도록 서로 대향되어 주위 환경으로의 자기장 반경을 감소시킨다.
