Abstract:
Apparatus and methods for power amplifiers with positive envelope feedback are provided herein. In certain implementations, a power amplifier system includes a power amplification stage that amplifies a radio frequency signal, at least one envelope detector that generates one or more detection signals indicating an output signal envelope of the power amplification stage, and a wideband feedback circuit that provides positive envelope feedback to a bias of the power amplification stage based on the one or more detection signals. The power amplifier system further includes a supply modulator that controls a voltage level of a supply voltage of the power amplification stage based on the one or more detection signals such that the supply voltage is modulated with the output signal envelope through positive envelope feedback.

Claim (Index 4):
The power amplifier system of  claim 3  wherein the wideband voltage shifter includes a first resistor including a first end configured to receive a first detection signal of the one or more detection signals and a second end configured to generate a positive envelope feedback signal operable to control the bias of the power amplification stage.
