Abstract
Devices and methods for correcting for start-up transients in integrated power amplifier are disclosed. A power amplifier is responsive to a bias control output and is arranged to provide an amplified power output. In some examples, the boost current is adjusted based on a supply voltage and an input power of the power amplifier. The power amplifier can operate in a low power and a high power mode and the adjustments can be made to the supply voltage and/or the input power vary depending on whether the power amplifier is operating in the high or low power mode. The adjustments for the high power mode operation are different than and correspond to the high power mode input power and voltage and the adjustments for the low power mode operation are different than and correspond to the low power mode input power and voltage.
