The transport properties of a coherent conductor depend on the surrounding circuit. First, electronic quantum interferences blend the conductor with its vicinity, resulting in a different coherent ...

The pristine, regimented symmetry of digital circuit boards is occasionally interrupted by an irregular huddle of linear components. These aberrants are tolerated because they perform a variety of ...

A simple logic probe in concert with a signal source can be used to check digital as well as linear circuits. With the flick of a switch, the probe can inject a test signal or check the logic state of ...

When we think about signals and systems, we often do so with an emphasis on creating and transmitting signals with specific characteristics. That is, we want the signal to have some desired amplitude, ...

A variety of linear models are available to represent common active electronic devices such as transistors and vacuum tubes. Devices operating under large-signal conditions often require nonlinear ...

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...

As part of writing tech stories such as those we feature here at Hackaday, there is a huge amount of research to be done. We trawl through pages and pages of obscure blogs, videos, and data sheets.

Bob Widlar (1937-1991) is without a doubt one of the most famous hardware engineers of all time. In fact, it would not be an exaggeration to say that he is the person who single-handedly started the ...
