GALS (Globally Asynchronous Locally Synchronous) 시스템 기반의 SoC 설계에 필수적인 DI (Delay Insensitive) 데이터 전송방식 중 기존의 전압 모드 기반 설계 방식은 N 비트 데이터 전송에 물리적으로 2N+1 개의 도선이 필요하다. 이로 인한 전력 소모와 설계 복잡성을 줄이기 위해 N+1 개의 도선으로 N 비트 데이터를 전송할 수 있는 전류 모드 다치 논리 회로 기반 설계 방식이 연구되었다. 그러나, static 전력의 비중이 커 데이터 전송 속도가 낮을수록 전력 소모 측면에서 취약하고, 휴지 모드에서도 상당량의 전력을 소비한다. 본 논문에서는 이러한 문제점을 해결할 수 있는 전류 모드 기반 인코더와 디코더 회로를 제안하고, 이에 따른 새로운 전류 인코딩 기법을 설명한다. 마지막으로 기존의 전압 모드 및 전류 모드 방식과 delay, 전력 소비 측면에서 비교 데이터를 제시한다.
