The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is … ...

AND gate implemented as diode-resistor logic. (Credit: Anthony Francis-Jones) The fun part about logic gates is that there are so many ways to make them, with each approach having its own ...

When designing logic for higher-than-usual supply voltages, suchas 24V, you can use a voltage regulatorwith a standard logic family and interfaceit through level shifters.Alternatively, if the logic ...

If the standard AND or OR logic elements are easily replaced by diode-resistive circuits, then the situation is much more complicated for XOR elements. It is worth noting that 3XOR logic gates are not ...

Diodes, logic gates and sensors can be built from metal nanoparticles coated with charged organic ligands. Nanoparticles have been used extensively as an electrode material 7,8, but are generally ...

While memristors cannot support standard transistor-like logic, they can implement a form of diode logic. Strukov’s team then developed another integrated architecture for logic using a two-layer ...

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 ...

Using DNA and harmless gut bacteria, scientists at Imperial College London have built biological logic gates that could lead to the development of a new generation of microscopic biological ...
