Abstract
Dynamic error vector magnitude correction for radio-frequency amplifiers. In some embodiments, a radio-frequency amplification system can include an amplifier configured to receive an input signal through an input path and generate an amplified signal, a power adjustment component implemented along the input path and configured to adjust power of the input signal, and a control circuit configured to provide a control signal to the power adjustment component based on an operating condition associated with the amplifier, such that an impact of the operating condition on the amplifier is compensated by the adjusted power of the input signal.
