Abstract
A method and apparatus are provided for reducing power dissipated by an amplifier circuit such as a line driver in a Digital Subscriber Line (DSL), a power amplifier in a radio environment, etc. The power supplied to the amplifier circuit changes depending upon the level of input signal to the amplifier circuit. A higher power is supplied to the amplifier circuit when the level of the input signal exceeds a threshold. Otherwise, a lower power is supplied to the amplifier circuit.
