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 … ...

Traditional inverters – NOT gates – are already made with diodes (typically not light-emitting), resistors (typically not light-dependent), and bipolar transistors.

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 ...

Physicists at the University of California, Riverside have received a $2 million research grant to work on "magnetologic gates," a brand new computing building block made from graphene and ...
