Dynaco hasn’t made equipment in decades. Yet it’s still a name most audiophiles know off-hand. That’s because the American manufacturer left an indelible legacy on the world of hi-fi, thanks in large ...

The first installment of this series introduced the boundary plot, an often-misunderstood plot found in instrumentation amplifier (IA) datasheets. It also discussed various IA topologies: traditional ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier configurations. This doesn’t come up as often as it used to, but it is still a good ...

Abstract: A Doherty power amplifier is introduced that uses a hybrid combination of common-emitter (CE) and common-base (CB) devices for operation above 100 GHz. The use of CE and CB devices ...

The common emitter amplifier is one of three basic single-stage amplifier topologies. The BJT version functions as an inverting voltage amplifier. The base terminal of the transistor serves as the ...

In today’s information-driven society, there’s an ever-increasing preference to measure phenomena such as temperature, pressure, light, force, voltage and current. These measurements can be used in a ...

Jennifer Hudson is telling you she’s not goin’ away from Common. Nearly two years after confirming her relationship with the “Glory” artist on her eponymous talk show, the American Idol alum reflected ...

Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure ...

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

The Enquirer's Just Askin' series aims to answer the questions that no one seems to have an answer for, not even Google. Question: What's the most common name for a city in the United States? Here's a ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...
