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 ...

Class D audio amplifiers have been increasingly famous in the recent years. This article will present the what’s, why’s and how’s of Class-D audio amplifiers. The article will also present audio ...

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 ...

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 ...

Consumer demand for flexible audio features and hi-fi sound from mobile phones has led to handset audio chip designers having to optimise the Class D amplifier to meet the noise and power management ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

A little of the old, a little of the new—here's a quick brushup on amplifier lore. Amplifiers are fundamental circuit-design elements. They drive everything from earbuds to antennas. Placed ahead of ...

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 ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...
