As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits. Herein, by making use of the hybridization and displacement of DNA ...

Half adder is a combinational circuit that performs simple addition of two binary numbers. The input variables designate the augend and addend bits; the output variables produce the sum and carry. It ...

Arithmetic circuits such as the digital adder and subtractor are simple combinational logic. In this lab, students learn to construct a 2-bit full adder/subtractor from basic combinational logic.

One of the major challenges of VLSI circuits is heat caused by energy loss. One of the successful solutions to this challenge is to design circuits in a reversible manner. Hence, the design of ...
