whereas half adder has only two inputs and two outputs. The first two inputs are A and B and the third input is an input carry as C-IN. When a full-adder logic is designed, you string eight of them together to create a byte-wide adder and cascade the ...
Ultracompact chip-integrated all-optical half- and full-adders are realized based on signal-light induced plasmonic-nanocavity-modes shift in a planar plasmonic microstructure covered with a nonlinear nanocomposite layer, which can be directly integrated
It is used to design different types of logic gates and logic circuits. In this chapter, we have utilized it to design a frequency-encoded optical XOR gate, half adder, and half subtractor using TOAD-based switch for the first time. The input/output bit patterns along with ON/OFF ratio ...
