In this tutorial, we will learn about the half and full subtractors, designing of full subtractor using half subtractor in Digital Electronics.
The half-subtractor comprises an XOR gate, an AND gate, and a NOT gate. The XOR gate is realized using semiconductor optical amplifier (SOA)-based Mach鈥揨ehnder interferometer (MZI). The AND, OR, and NOT gates are based on nonlinear properties of semiconductor optical amplifier. The ...
A Full Adder can also be implemented using two half adders and one OR gate. The circuit diagram for this can be drawn as, And, it could be represented in block diagram as, The Boolean expression for Sum and Carry is as, Sum = A⊕B⊕C Carry = AB + (A⊕B). C = AB + (...
From the above information, by evaluating the adder, full subtractor using two half subtractor circuits, and its tabular forms, one can notice that Dout in the full-subtractor is accurately similar to the Sout of the full-adder. The only variation is that A (input variable) is complemented i...

This work indicates that the realization of the full adder and full subtractor using DNA self-assembly are carried with parallel logic gates operations. The method that we discuss here are fundamental to the logical operations, but it seems possible to further extend more complex logic circuits ...
Over the past decade, DNA has demonstrated remarkable potential in fabrication of molecular logic and arithmetic systems. In this work, a simple DNA-based system mimicking a full-subtractor that handles three inputs including one minuend and two subtrahe
