Several years ago we were developing a clamp-on photometer, a hand-held instrument that could be clamped onto a communications optical fiber to indicate the presence of light, its direction of travel, ...

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a ...

Traditional digital comparator ICs are electronic analogs of mechanical lever scales. Like their mechanical counterparts, they compare two logical signals and produce an output (typically a voltage ...

Low-power high-speed CMOS comparators and analog-to-digital converters (ADCs) play a pivotal role in modern electronics, from data-intensive computing systems to precision biomedical instrumentation.
