This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a ...

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

Digital logic circuits generally have input power and ground connections in addition to their logic connection points, so [Thomas]’s main breakthrough here is that the mechanical equivalent ...

Digital gates are fundamentally analog in nature. They use transistors. Sure, these transistors are operated at their conduction extremes (which is why they are called “digital”), but during the logic ...

In fact, there are two different D Flip Flops: one is a single gate, and the other is a module with anywhere between 1 and 26 gates. With the addition of some extra addressing logic, which is included ...

A recent paper in Nature Communications discusses how to 3D print common logic gates using both macro-scale 3D printing techniques and a much smaller version with microstereolithography.

Scientists at Johns Hopkins have engineered cells that behave like AND and OR Boolean logic gates, taking an important step toward using living cells to create computer circuits. While previous ...

From Gates to Systems Boolean gates make up circuits, and circuits make up electronic systems. This circuit adds two bits together (for details, see Boolean logic).

Synthetic biology researchers have demonstrated a new method for digital information processing in living cells, analogous to the logic gates used in electric circuits. The circuits are the ...
