The most common audio power amplifier operates in the Class-AB mode. It provides the greatest amount of output power with the least amount of distortion. The downside is that it consumes quite a bit ...

Meylan, France - February 4, 2008 - The pressure to lowering the power consumption leads system designers to investigate different architectures for audio amplifiers. They naturally investigate ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the linear signal that is typical in class-AB amplifiers. The PWM signal contains the audio signal and the PWM switching frequency ...

A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

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 ...

Class D circuit seems to be the new favorite flavor for some. They are very inexpensive and provide outstanding sound quality for the price. Compared to other amplifier circuit topologies such as ...

Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...

Hang around in any of the many guitar or audiophile forums or discussion boards for long enough, and eventually you’ll come across the arguments over amplifier topologies. One of the more interesting ...

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 ...
