Novel Design of Ternary Arithmetic Circuits

Over the few decades, complementary metal oxide semiconductor technology has led to

thedevelopment of digital systems. However, the dimension scaling of CMOS approach is limit, to

overcome this disadvantage carbon nano tube FETS (CNTFETs) are came into existence. Here

changing of the thresholdvoltageofthe CNTFETs are possible by varyingitsdimensions(length,

width). They enable new paradigms in circuit designs, such as muti valued logic(MVL). These

circuits focus on minimizing the hardware cost by processing more than twovalues per elementary

operation. Therefore, it reduces the inter connection complexity ofdigitalsystemscomparedthat

ofbinary logiccircuits.

Arithmetic circuits are playing an important key role in many electronic systems

suchasmicroprocessorsanddigitalsignalprocessorswithhighefficiency.Theefficiencyofthesystemsare

mainlyevaluatedbytheirarithmeticcircuit’scapability.WiththehelpoftheseCNTFETS, the design of

arithmetic circuits like half adder and multiplier will be proposedTheaboveproposedhalfadderand
