Abstract:
An audio reproduction apparatus is shown and includes an amplifier with a power amplification stage having transistors in a push-pull arrangement. A bias generator biases the transistors with a standing current. A processor receives a data stream comprising digital samples of an analog audio signal and analyzes the peak level of each group. It then determines the appropriate standing currents to maintain Class A operation of the power amplification stage given the peak levels of each of the groups. A digital to analog converter produces an analog input signal for the input stage of the amplifier from the data stream. A feedforward path between the processor and the bias generator allows the standing current to be adjusted prior to the arrival of the analog input signal in the power amplification stage.

Claim (Index 16):
The apparatus of  claim 11 , in which the processor is further configured to:\n determine an appropriate supply voltage for the power amplification stage given the peak level of the digital samples; and adjust the supply voltage for the power amplification stage before the arrival of the analog input signal in the power amplification stage.
