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% ...
Here is a thorough treatment of distortion in RF power amplifiers. This unique resource offers expert guidance in designing easily linearizable systems that have low memory effects. It offers you a detailed understanding of how the matching impedances of a power amplifier and other RF circuits can...

In this paper, a theoretical investigation of the causes of the AM/PM distortion in Doherty Power Amplifiers is presented for the first time. The distortion sources are identified and a solution to mitigate the AM/PM conversion through the input termination of the Carrier amplifier is also highli...
The continuing popularity of tube amplifiers among the audiophile community would tend to indicate that at least some forms of distortion are perceived as pleasing. In terms of simple harmonic distortion, it is often asserted that even-order distortion products have a more musical relationship to ...
Design of Wide-band Power Amplifier based on Power Combiner Technique with Low Intermodulation Distortion RF power amplifiers are one of challenging blocks in designing radio frequency transceivers, this is due to non-linearity behavior of power amplifiers that leads to inter-modulation distortion. This...
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...
