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 ...

As Moore's Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as "lightwave electronics" ...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make up ...

Any typical digital design style with CMOS uses complementary pairs of p-type and n-type MOSFETs for logic functions implementation. Naturally, CMOS always ought to provide INVERTED outputs like ...

We can represent Boolean logic by creating circuit diagrams that combine simple logic gates. Logic gates can be built up into chains of logical decisions. Some logic gates may have more than two ...

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, ...
