Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computatio… ...

Using DNA and harmless gut bacteria, scientists at Imperial College London have built biological logic gates that could lead to the development of a new generation of microscopic biological ...

Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following examples. Transistors make up gates, gates make up circuits, and circuits make up electronic systems.

To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (W… ...

By using water, tubes, and 3D printed components, Mould demonstrates that the principles of logic gates can be applied in a physical and visual manner.

Various logic gates—AND, OR, XOR, NAND, NOT, CNOT, and a half adder—could be put together using different combinations of robots. The DNA gates all take two inputs in the form of other molecules.

For example, we might require only four of the six NOT gates in a 74x04 package or only three of the four 2-input AND gates in a 74x08 part. In Part 1 of this 2-part mini-series, we considered what to ...

A new class of logic gates offers robust characteristics, low power consumption, and the ability to run on a very wide range of supply voltages.
