Contemporary logic circuits use MOSFETs as the elements to build gates, but there are many ways to implement them. Using relays is one of them, and you can literally see how they work.

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

“In this paper, we propose a non-traditional design of dynamic logic circuits using Fully-Depleted Silicon on Insulator (FDSOI) FETs. FDSOI FET allows the threshold voltage ( V t) to be adjustable ...

Here, we address these issues, advancing the art of engineering living digital circuits by focusing on two main engineering goals. First, we built a universal, single-gene NOR logic gate ...

When pulsed at their inputs, they change their state. To learn how gates work in a circuit, see Boolean logic. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

Another plus of the featured circuit is the fact that it uses a 7486 IC for the XOR gate. Since this IC has 4 gates inside, the circuit can be expanded to build a four channel logic analyzer.

simple circuit to behave like any kind of logic gate. Such a chip could be transformed, for example, from a graphics card into a memory chip and back again – in just two computer clock cycles.

The resulting output (Figure 2) doubles an input frequency from 15MHz to 30MHz. A few simple selections configure this circuit for an application. The logic gate must operate from the desired supply ...

He’s solved that with a unique mechanical amplifier. Digital logic circuits generally have input power and ground connections in addition to their logic connection points, so [Thomas]’s main ...
