Efficiency of Low Power Audio Amplifiers and Loudspeakers
In this paper we look at the load presented to audio amplifiers by real transducers. We consider the power losses in Class-AB and Class-D amplifier topologies, and determine that in order to predict efficiency it is necessary to consider the amplifier/transducer combination. The ability of the class-D amplifier to recycle quadrature load current offers new ways to improve efficiency. INTRODUCTI...

متن کاملTransient Distortion in Transistorized Audio Power Amplifiers
This paper discusses a new kind of distortion mechanism found in transistorized audio power amplifiers. It is shown that this distortion arises from the multistage feedback loop found in most high-quality amplifiers, provided that the open-loop transient response of the power amplifier is slower than the transient response of the preamplifier. The results of the analysis are verified by measure...
متن کامل3-D Audio Using Loudspeakers
3-D audio systems, which can surround a listener with sounds at arbitrary locations, are an important part of immersive interfaces. A new approach is presented for implementing 3-D audio using a pair of conventional loudspeakers. The new idea is to use the tracked position of the listener's head to optimize the acoustical presentation, and thus produce a much more realistic illusion over a larg...
متن کاملImproving the Linearity and Efficiency of RF Power Amplifiers
Agrowing number of semiconductor technologies are being applied to RF power transistor applications. These technologies include Si LDMOS FET, SiGe HBT, InGaP HBT, GaAs MESFET, AlGaAs pHEMT, SiC MESFET and AlGaN/GaN HEMT. The dependencies of linearity and efficiency of such technologies are often common, such as transconductance derivatives, capacitance variations, breakdown effects and parasiti...
