The leakiness of commonly used genetic components can make the construction of complex synthetic circuits difficult. Here the authors construct NOR gate architecture, using dCas9 fused to the ...

Transistors to Gates to Circuits This illustration of a half-adder circuit, which adds one bit to another, depicts logic gates as mechanical switches rather than semiconductor devices.

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 ...

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 ...

Logic gates are the basic building blocks of digital circuits. Molecular electronic devices were proposed about 40 years ago.

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.

Here is a very nice project that [Znaxque] finished a few months ago: a simple nixie clock made with logic gates only. In this build, the mains 50Hz is used as a time base instead of a 32KHz crysta… ...

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 ...
