A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...

As Moore's Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as "lightwave electronics" ...

Logic elements “Exclusive OR” are widely used in a variety of digital devices. However, in some cases, for example, when using increased operating voltages, the use of standard chips is impossible.

New artificial proteins have been created to function as molecular logic gates. Like their electronic counterparts in computers, these biochemical tools can be used to program the behavior of complex ...
