I find that if I’m trying to make a point with a student or a colleague about a circuit, sometimes the Falstad online simulator is worth a few thousand words. You can draw the circuit, play w… ...

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 circuits successfully performed the sum-of-product operation at 2.8 kHz. The full potential of memristors was demonstrated when the devices were made to actively re-program themselves.

Logic gates take an input of True or False and give an output of True or False. Each operator has a standard symbol that can be used when drawing logic gate circuits.

Researchers have built logic circuits, the heart of all electronic gadgets, on molybdenum disulfide films that are two molecular layers thick (Nano Lett., DOI: 10.1021/nl302015v). The devices are ...

Conventional wisdom says you can’t build a flip-flop with just one transistor, but here we are. [roelh] has built a flip-flop circuit using only one transistor and some bizarre logic that’s ...

Xie has developed a genetic “logic circuit” that prompts cells to kill themselves if the levels of five molecules match those of a cancer cell.
