Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

Editor's note: this is the final installment in this series. Part one is available at http://www.audiodesignline.com/howto/199202502 At 15 dB to 12 dB even very dense ...

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 ...

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 ...

Dissipation consists mainly of resistive losses, (Output Current) 2 * R. Figure 3 illustrates the efficiency of the sinewave input and also shows the distortion of the output signal. That distortion ...
