Operational amplifiers (op amps) have proliferated from specialized instruments made from large tubes to tiny monolithic circuits composed of a sliver of silicon, germanium or gallium arsenide. Dozens ...

Zero-drift operational amplifiers have proven to be valuable problem solvers due to their low input offset voltage and minimal input offset voltage drift. Rail-to-rail input versions of these ...

Scientists have developed a chip smaller than a strawberry seed to boost space communications. The tiny signal amplifier is aimed at making future radar-observing and telecommunications space missions ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...

Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to ...

In the years before World War II it was theorized that shortwave radio waves could propagate through the ionosphere relatively undisturbed and allow for a signal to be bounced off the moon and ...
