Design of ternary adiabatic gated serial data comparator

By researching the working principle and structure of comparators,multiple-valued logic circuits,and adiabatic circuits,a novel design of ternary adiabatic gated serial comparator which adopts high priority comparison was proposed.The ternary adiabatic gated serial data comparator is composed of literal circuit and one bit ternary adiabatic comparator,which the component-level function expressions and the corresponding circuits can be derived by using the theory of three essential circuit elements.PSPICE simulation results validated that the proposed circuits have correct logic function and the characteristics of energy injection and recovery.Compared with traditional ternary CMOS high priority comparison serial comparator,the energy saving can be achieved about 90%.
