In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...

Straight out of the golden age of DIY electronics, the Digital Wooing Aid circuit turns TTL logic into tender words. It’s ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

Researchers have built logic circuits, the heart of all electronic gadgets, on molybdenum disulfide films that are two molecular layers thick (Nano Lett., DOI: 10.1021/nl302015v). The devices are the ...

Graphene is a single-atom thick carbon crystal with unique properties beneficial for electronics including extremely high electron mobility and phonon thermal conductivity. However, graphene does not ...

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 ...

In new research, Alex Green, an assistant professor at ASU’s Biodesign Institute, demonstrates how living cells can be induced to carry out computations in the manner of tiny robots or computers. The ...
