The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

As you probably know, processors – and most other digital technology – are made up of transistors. The simplest way to think of a transistor is as a controllable switch with three pins. When the gate ...

A technical paper titled “The RGATE: an 8-in-1 Polymorphic Logic Gate Built from Reconfigurable Field Effect Transistors” was published by researchers at TU Dresden and NaMLab. “We present the ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...

Physicists at the University of California, Riverside have received a $1.85 million research grant to work on "magnetologic gates," a brand new computing building block made from graphene and magnetic ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

The newly developed logic circuits are equipped with diamond-based MOSFETs (metal-oxide-semiconductor field-effect-transistors), and they have two different operation modes. The different modes are a ...

This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a ...

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).

For decades, chipmakers have squeezed more computing power out of silicon by shrinking transistors, but that strategy is ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...
