The schematic from the very first test shows the slight modifications [Dr. Cockroach] made to incorporate light into the logic gate using a 910 Ohm, output LED, and an LED and LDR in parallel.

Photons (or light) travel faster and more efficiently than electrons. That’s why we’ve been pushing for the use of fiber optic cables for long-distance data transmission.

The exact processing rules depend on the kind of logic gate implementing them, but for example, an AND gate only outputs a 1 if both its inputs are 1, otherwise it outputs a 0. In the researchers’ new ...

Logic gates take two inputs, compare them, and then output a signal based on the result. They can, for example, output a 1 if both incoming signals are a 1 or a 0, or if either or neither of them ...

Light takes over: Researchers demonstrate logic gates without electricity It's just a proof-of-concept for now, but the scientists are dreaming big By Zo Ahmed September 4, 2024, 10:41 ...

Optical computing, involving on-chip integrated logic units, could provide improved performance over semiconductor-based computing. Here, a binary NOR gate is developed from cascaded OR and NOT ...

It's time to dig inside to understand how the internal CPU components are designed. We'll discuss transistors, logic gates, power and clock delivery, design synthesis, and verification.

Binary logic gates take a combination of two 1s and 0s, and output different results based on what kind of gate it is. Ternary logic gates do the same thing, except with three possible inputs and ...

DNA-based logic gates that could carry out calculations inside the body have been constructed for the first time. The work brings the prospect of injectable biocomputers programmed to target ...
