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 ...

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 ...

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

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, ...

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 ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

Researchers have engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations. A team of UCSF researchers has ...
