Figure 2: The circuit doubles a 15MHz input frequency to 30MHz. A few simple selections configure this circuit for an application. The logic gate must operate from the desired supply voltage and ...

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 ...

The novel chips work by exploiting inherent “chaotic” behavior within the integrated circuits, enabling a single, simple circuit to behave like any kind of logic gate.

The Nature paper describes how the Voigt team built simple logic gates out of genes and inserted them into separate E. coli strains. The gate controls the release and sensing of a chemical signal, ...

Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...
