Abstract:
Described herein are power amplifier (PA) architectures that improve PA performance (e.g., efficiency, linearity, etc.) over an extended range of the operating power levels of the PA. These architectures can be implemented on a single chip to provide a single-chip standalone PA solution. This improvement comes with little additional complexity, little additional current consumption, and/or little additional chip area. The architectures utilize a dynamic biasing technique using positive envelope feedback based at least in part on an instantaneous envelope signal at an output of a power amplifier.

Claim (Index 15):
A radio-frequency (RF) module comprising:\n a packaging substrate configured to receive a plurality of components; and a power amplification system implemented on the packaging substrate, the power amplification system including a multi-stage amplifier configured to provide an amplified output signal having an envelope, an envelope detector configured to detect the envelope of the amplified output signal, and a resistive voltage shifter configured to generate a dynamic bias signal related to the detected envelope of the amplified output signal and to provide the dynamic bias signal to the multi-stage amplifier.
