본 논문에서는 다운 디지털 회로(DLC)를 이용하여 4치 논리 게이트를 설계하였고, 이들 게이트를 이용하여 동기식 4치 up/down 카운터를 제안하였다. 제안된 카운터는 T-type 4치 플립플롭과 $2\times1$ 임계-t 멀티플렉서로 이루어져 있고, T-type 4치 플립플롭은 D-type 4치 플립플롭과 4치 논리 게이트들(모듈러-4 가산 게이트, 4치 인버터, 항등 셀, $4\times1$ 멀티플렉서)로 구성되어 있다. 이 카운터의 모의실험 결과는 10[ns]의 지연시간과 8.48[mW]의 전력소모를 보여준다. 또한 다치논리 회로로 설계된 카운터는 상호결선과 칩 면적의 감소뿐만 아니라 디지트 확장의 용이함의 이점을 가진다.

In this paper, quaternary logic gates using Down literal circuit(DLC) has been designed, and then synchronous Quaternary un/down counter using those gates has been proposed The proposed counter consists of T-type quaternary flip flop and 1-of-2 threshold-t MUX, and T-type quaternary flip flop consists of D-type quaternary flip flop and quaternary logic gates(modulo-4 addition gates, Quaternary inverter, identity cell, 1-of-4 MUX). The simulation result of this counter show delay time of 10[ns] and power consumption of 8.48[mW]. Also, assigning the designed counter to MVL(Multiple-valued Logic) circuit, it has advantages of the reduced interconnection and chip area as well as easy expansion of digit.
