Abstract: A general method for designing ternary circuits using double pass-transistor logic is investigated.The logical relation of each MOS transistor is formulated by using the transmission operation in order to make effective and practical use of the circuits.A way to generate ternary complementary and dual circuits by applying the complementarity and duality principles is presented.This new static ternary double pass-transistor logic scheme has some favorable properties:the use of standard CMOS process without any modification of the thresholds,a perfectly symmetrical structure,a full logic swing,the maximum possible noise margins,a less complex structure,and no static power consumption.HSPICE simulations using TSMC 0.25μm CMOS technology and a 3V power supply demonstrate the effectiveness of the proposed design.
