Amplifier designer Douglas Self discusses Class-A amplifier output topologies, quiescent current and some actual Class-A audio amplifier designs in the eighth and final article in the Distortion in power amplifiers series.Douglas SelfEetimes Com
Considering the economic importance of audio power amplifiers, surprisingly little reliable information has been published on their design. Distortion in particular has been neglected, although it is the most variable feature of amplifier performance. You may have two units placed side, one giving 2% ...
Harmonic distortion in power amplifiers are mainly caused by the non linearities of the active elements (transistors). The active element used for amplification whether BJT, FET, MOSFET or anything like that may not equally amplify every points in the input waveform and this is the reason behind ...

audibility of simple harmonic distortion at levels above approximately 2%, but it is not clear that all of these studies fully accounted for the distortion present in the loudspeakers required to perform the testing. The continuing popularity of tube amplifiers among the audiophile community would ...
The Digital Pre-distortion for Power amplifiers linearization is imposed by the new RF systems and RF frontends applications and designs. With the constant increase in the number channels, bandwidth, data throughput and antenna elements, stringent specifications are required for power, efficiency and ...
The present invention is directed to systems and methods for reducing the distortion of power amplifiers. In particular, methods and systems are described that enable a determination of a pre-distortion correction signal to be determined, which when added to the nominal signal, a reduction in the...
Power amplifier sharing in a wireless communication system with amplifier pre-distortion The technique of amplifier sharing is implemented in a system designed to accommodate transmit diversity. In one embodiment of the invention, the amplifiers are shared 1) to amplify a first and a second diversity...
