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 1):
A power amplifier architecture comprising:\n a multi-stage amplifier having an input port and an output port, the multi-stage amplifier to receive an input signal at the input port and to provide an amplified output signal at the output port; an envelope detector coupled to the output port of the multi-stage amplifier, the envelope detector configured to receive a signal corresponding to the amplified output signal and to generate an envelope signal related to an envelope of the amplified output signal; and a dynamic bias signal generator coupled to the envelope detector and to the multi-stage amplifier, the dynamic bias signal generator configured to receive the envelope signal from the envelope detector, to generate a dynamic bias signal related to the envelope of the amplified output signal, and to provide the dynamic bias signal to the multi-stage amplifier.
