In this digital era, all-optical logic gates (OLGs) proved its effectiveness in execution of high-speed computations. A unique construction an OR, NOR, and NAND based on the notion power combiner employing metal–insulator-metal (MIM) waveguide Y-shape with a minimal imprint 6.2 µm × 3 is presented structure evaluated by finite-difference time-domain (FDTD) technique. The insertion loss (IL) ext...

Testing of Sequential circuits can be done by two test vectors (all 1’s and all 0’s) if the circuits were based on the conservative logic. The circuit is made to be tested by designing the circuit with the help of Reversible logic gates. Toffoli gate is used as reversible gate in this paper. Sequential circuits such as latches, flip flops are designed with the help of conservative logic reversi...
