1. An amplification system comprising:
- a mode selector that controls operation of the amplification system between a component mode and a composite mode based on a characteristic of an input signal relative to a threshold level; and
an amplifier system having a plurality of amplifiers that cooperate to amplify components of the input signal in the component mode to provide a reconstructed amplified representation of the input signal and a single amplifier that amplifies the input signal in the composite mode to provide an amplified representation of the input signal.

Abstract
An amplification architecture or system is provided having a multiple amplifier system that switches modes of operation between operation in a component mode and a composite mode based on a characteristic of an input signal relative to a threshold level. In the component mode, the components of the input signal are employed to different terminals of the multiple amplifier system that provide a reconstructed amplified representation of the input signal. In the composite mode, the input signal is amplified to provide an amplified representation of the input signal.
