The transistor, an invention that heralded a new era in electronics, is the key component of practically all integrated circuits (ICs) and microprocessors. The point-contact transistor that Walter H.

On the path to exploring complex logic, let’s discuss the electrical properties that digital logic signals are comprised of. While there are many types of digital signals, here we are talking about ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

The circuit shown is a 3-input Resistor-Transistor Logic (RTL) gate. a. Write the truth table for the input combinations of 0V and 5V with respect to the ground. b. Based on the output from the truth ...

Physicists at the University of California, Riverside have received a $1.85 million research grant to work on "magnetologic gates," a brand new computing building block made from graphene and magnetic ...

Researchers in Sweden have created electronic circuits and devices that are integrated within living plant material. The team introduced a conductive polymer into the vascular system of plants, which ...

Silicon nanowires are one of the great hopes for electronic devices of the future. Unlike features carved using photolithography, nanowires are easy to make on a nanometre scale. Electronic engineers ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...
