Abstract
Devices and methods for correcting for start-up transients in integrated power amplifiers are disclosed. A delay element is arranged to produce a delay waveform signal that is responsive to an input voltage signal. A transconductance element has an input that receives the delay waveform signal and is arranged to provide an output boost current that is based on the delay waveform signal and a gain of the transconductance element. A reference element provides an output bias current that is responsive to a static reference current and the boost current. A bias element has an input that receives the bias current and is arranged to provide a bias control output. A power amplifier is responsive to the 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.
