Title: POWER AMPLIFICATION SYSTEM WITH ADAPTIVE BIAS CONTROL
Abstract:
Power amplification system with adaptive bias control. In some embodiments a power amplification system includes a power amplifier including a radio-frequency (RF) input terminal for receiving an RF signal, an RF output terminal for providing an amplified RF signal, a supply voltage terminal for receiving a power amplifier supply voltage to power the power amplifier, and one or more bias terminals for receiving one or more bias signals. The power amplification system also includes a bias controller configured to provide the one or more bias signals to the one or more bias terminals, at least one of the one or more bias signals being based on the power amplifier supply voltage.
