A High-Efficiency Audio Power Amplifier A compact audio amplifier with high power and low distortion has been developed. The supply voltage for the class-B output stage of the amplifier is varied with the input signal so that the voltage applied to the active output transistor is held small and constant, appreciably reducing transistor dissipation.

The theoretical best efficiency for a traditional linear-amplifier output stage is 78% (as mentioned earlier), but linear amplifiers exhibit that efficiency only at their peak output power. The output stage of a Class D amplifier, in contrast, delivers a maximum theoretical efficiency of 100% over its full dynamic range, and with sub-1% THD.

because high efficiency means that the batteries last longer. In order to determine the efficiency of a power amplifier, firstly it is neces-sary to determine the DC power supplied by the DC power source to the amplifier, PDC. The power supplied by a DC voltage source, V CC, is given by: PV DC = CCI DC (12.1) where I DC
What are amplifier classes and their power efficiencies?

The efficiency of Class C amplifiers can be fairly high, up to about 70-80%, but because the distortion is also high (10 to 30%) the Class C approach cannot be used for audio. However, it is used for higher-power RF transmitters, where dissipation must be kept to acceptably low levels.
