- 초전도체 단자속양자소자를 논리회로로서 사용한 반가산기와, 상기한 반가산기의 합단자 및 캐리단자에 입력단이 연결되어 있으며 상기한 반가산기의 출력신호를 이용하여 오아 게이트, 앤드 게이트, 애드 연산 게이트, 익스클루시브 오아 게이트 등으로 작동하도록 하는 스위치부를 포함하여 이루어지며,상기한 스위치부는, 상기한 반가산기의 합출력단에 입력단이 연결되어 있는 제1 스위치와, 상기한 반가산기의 캐리출력단에 입력단이 연결되어 있으며 상기한 제1 스위치의 출력단에 출력단이 연결되어 있는 제2 스위치와, 상기한 반가산기의 캐리출력단에 입력단이 연결되어 있는 제3 스위치를 포함하여 이루어지며,상기한 제1 내지 제3 스위치는 두 개의 초전도체를 약하게 결합시킨 조셉슨 접합들을 포함하여 이루어지며,상기한 스위치는 제어신호의 전류의 양이 회로요소들의 값들에 의해 정해지는 일정 값 이상이면 닫히게 되고 그 이하이면 열려있게 되는 구조로 이루어짐으로써, 입력신호(Data in)가 입력 인덕터를 통하여 들어오게 되면, 스위치의 조건에 따라, 스위치가 열려있으면 제1 조셉슨 접합(Joff)에 전압펄스를 일으켜 출력 펄스가 발생하지 않고, 스위치가 닫혀있으면 제2 조셉슨 접합(Jon)에 전압펄스를 일으켜 출력 인덕터를 통하여 출력 펄스가 발생하는 구조로 이루어지며,상기한 애드 연산 게이트는, 각각 2 비트로 구성된 두 개의 입력, 예를 들면 11(A1=1, A0=1)과 10(B1=1, B0=0)이 가해지면 각 자릿수의 애드값이 R2, R1, R0의 출력단에 나타나게 되어 101(R2=1, R1=0, R0=1)의 출력 값을 얻게 되는 것을 특징으로 하는 반가산기를 이용한 논리연산장치.
