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 computations ...

The PAL family continued to evolve into the late 1980s, with faster, lower-power devices, including ones that could be reprogrammed. The most complex device type developed was probably the PAL22V10, ...

Building logic gates out of silicon is old hat, as is building them from discrete transistors, 555 chips, LEGO, and even gears. [Yukio-Pegio Gunji] and [Yuta Nishiyama] from Kobe University, along ...

This video explains how transistors work and how they are used to switch and amplify electrical signals in electronic ...

For the past several years, researchers have been creating living logic gates, using the genetic on and off switches we've discovered in the biochemical world to create simple logical functions. But ...

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 ...

Individual molecules have been demonstrated to exhibit promising applications as functional components in the fabrication of computing nanocircuits. Based on their advantage in chemical tailorability, ...

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 ...
