چکیده
High speed Full-Adder (FA) module is an important element in designing high performance arithmetic circuits. In this paper, I propose a high speed multiple-valued logic FA module. The proposed FA is designed and constructed with the use of 3 capacitors and 14 transistors, wh e r e t h e t r a n s i s t or s a r e c o n s t r u c t e d b y carbon nano-tube field effect transistor (CNFET) technology. Furthermore, my proposed technique has been examined in different voltages (i.e., 0.65v and 0.9v). The observed results reveal power consumption and power delay product (PDP) improvements compared to existing FA counterparts.
