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 ...

Perhaps our future overlords won’t be made up of electrical circuits after all but will instead be soft-bodied like ourselves. However, their design will have its origins in electrical analog… ...

DNA Strands Weaved into High-Complexity Logic Circuits and Multiple "Robot Arms" DNA computing may scale up dramatically by taking a page from the electronic world By JR Minkel Technology ...

Various logic gates—AND, OR, XOR, NAND, NOT, CNOT, and a half adder—could be put together using different combinations of robots. The DNA gates all take two inputs in the form of other molecules.

One of the elements is known as a NAND gate. It’s one of two basic logic gates that can be used to construct any other logic gate, and as a result, any kind of integrated circuit.

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 ...
