Abstract:
This paper proposes a novel design of 1-bit ternary magnitude comparator (TMC) using carbon nano tube field effect transistors (CNTFETs). The proposed 1-bit TMC is designed for pass transistor logic style in order to achieve low transistor count. Further, proposed design is used in realization of n-bit TMC which utilizes static binary tree configuration to correct the voltage levels and minimizes the number of stages to get high performance. Synopsis Hspice simulation results demonstrate that the proposed TMC for 4-bit operand length is 15% faster or 14% energy efficient with 32% less number of transistors, in comparison with CNTFET-based designs, recently published in the literature.
