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.

coli metabolism and cell division, demonstrating the capability to combine multiple logic gates for processing various signals and complex inputs. They used this circuit to control cell morphology ...

Precise control over processing ... Here we report integrated chemical logic gates based on ion bipolar junction transistors. Inverters and NAND gates of both npn type and complementary type ...

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 ...

A PWM-controlled regulator, this time using a logic gate IC, op-amp, and resistors and capacitors to buffer the PWM signal.

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.

Logic Gates are among the important components of a circuit. All the logical operations required to perform a particular task in an electronic circuit are carried by these logic gates. If you are ...

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.

The underlying circuits are a complex, networked system of logic gates that generate binary input and output signals controlled by electrons as signal carriers. A long-cherished dream is to ...

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 ...
