Carbon Nanotube filed-effect transistor (CNFET) is one of the promising alternatives to the MOS transistors. The geometrydependent threshold voltage is one of the CNFET characteristics, which is used in the proposed design. In this paper, we present a novel high speed Adder-subtractor cell using CNFETs based on XOR gates and multiplexer. Presented design uses fourteen transistors, ten for full ...

Abstract Nanophotonic arithmetic circuits requiring cascaded Boolean operations are difficult to implement due loss and footprint issues. In this work, we experimentally demonstrate plasmonic half-subtractor demultiplexer based on transmission-lines. Empowered by the unique polarization selectivity in surface plasmon modal behaviors, both realized without cascading. The of can be performed usin...

A series of complex logic gates were constructed based on graphene oxide and DNA-templated silver nanoclusters to perform both arithmetic and nonarithmetic functions. For the purpose of satisfying the requirements of progressive computational complexity and cost-effectiveness, a label-free and universal platform was developed by integration of various functions, including half adder, half subtr...

The paper presents current adder and subtractor circuits based on cascode current mirror with improved linearity and wide linear range.
