Abstract
A system for amplifying a signal with active power management according to one embodiment includes a first digital to analog converter (DAC) circuit configured to provide a modulated carrier signal; a amplifier circuit coupled to the first DAC, where the amplifier circuit is configured to amplify the modulated carrier signal; an output stage circuit coupled to the amplifier circuit, where the output stage circuit is configured to provide the amplified signal to a network; a second DAC circuit configured to provide a full wave rectified envelope of the modulated carrier signal; and a switching regulator circuit including a voltage reference input coupled to the second DAC circuit, where the switching regulator circuit is configured to provide a supply voltage to the output stage circuit and the supply voltage is modulated in response to the envelope received at the voltage reference input.
