Linear Power-Efficient RF Amplifier with Partial Positive Feedback
… To accommodate these high-PAPR signals, RF power amplifiers in mobile devices must operate under backed-off gain conditions, resulting in poor power efficiency. Various efficiency-enhancement solutions have been realized for backed-off devices to combat this issue.</p> <p>A brief overview of one …
