In this paper, realization of three fundamental functions, NOT,negated MAX and negated MIN functions, in the voltage-mode quaternarylogic is presented. First, the high-performance NOT circuits with thedown literal circuits are composed. The proposed NOT circuits have thequantified effect to realize high noise margins in the voltage-modequaternary logic circuits. Next, we propose the voltage comparator withthe NOT circuit, and, as applications of the voltage comparator, NMAXand NMIN circuits are designed. They can realize the negated MAX and thenegated MIN functions, respectively. The advantages of these proposedcircuits are fabrication with a conventional CMOS process, high noisemargins of more than 0.46[V] and low power consumption with peak of lessthan 350[μW] under 3.0[V] of the supply voltage in verification usingHSPICE simulations
