If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

The circuit was constructed around the functionality of a Class A amplifier to create a headphone circuit. BC308 – an epitaxial planar PNP transistor used for general purpose and low noise amplifier ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

High-fidelity sound reproduction enthusiasts are the latest beneficiaries of Gallium Nitride (GaN)’sfundamental qualities, as it provided these audiophiles respite in their challenging environment.

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier that ...

Amplifiers are fundamental circuit-design elements. They drive everything from earbuds to antennas. Placed ahead of analog-to-digital converters (ADCs), they reshape signals from sources as diverse as ...

Krell announced the most revolutionary design change in its 33-year history: iBias, a patent-pending new technology that uses the Class A circuitry preferred by audiophiles yet consumes far less ...
