Abstract: Two tunnel-diode logic circuits are discussed giving "AND-OR" or "NOR" operation. Germanium coupling diodes are used to provide unilateral propagation with large fan-in, and a diode gate, ...

The familiar five volts standard from back in the TTL days always struck me as odd. Back when I was just a poor kid trying to ...

Electric-field-assisted assembly enables scalable, lithography-free fabrication of logic circuits using 2D semiconductors. It provides a practical route to high-performance electronics beyond ...

Abstract: Ternary logic circuits are considered a high-potential alternative that can continue the technological advance of binary logic. Current studies in ternary logic focus on two aspects: One ...

A single organic device reconfigures as transistor, rectifier and logic gate, offering compact circuits with higher ...

Transistors, the fundamental building blocks of digital logic, are now being made just a few dozen atoms wide. At these incredibly small scales, traditional silicon fabrication faces significant ...

An isolated comparator is fundamentally different from a standard comparator, and the comparison happens on the input side.

Many recent Design Ideas have involved button-pushing to control power. Some may have been more resistant to contact-bounce than others—but how can we really check that? This DI describes how some ...

Laser method could help to pinpoint the age of many fossils, but some palaeontologists say further research is needed to verify the technique. Scientists in China have calculated the direct age of a ...
