A new op-amp, which can function with a supply as low as 2 V, operates from a deeply discharged battery, extending the runtime of portable devices such as smoke alarms. Moreover, running at 2 V lets ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

This is an excerpt from “Self on Audio,” by Douglas Self, used with permission from Newnes Publishers, a division of Elsevier. For many years I felt that the output stages of power amplifiers ...

Most hobby-grade software defined radio setups don’t transmit. Of the few that do, most of them put out anemic levels around one milliwatt or so. If you want to do something outside of the lab, you’ll ...

Quad announced the Elite QSP stereo power amplifier with their latest Current Dumping technology to deliver an awesome sound from a compact package. The Elite QSP — which stands for Quad Stereo Power ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.
