Abstract: Devices and methods for correcting for start-up transients in integrated power amplifiers are disclosed. A delay element (116) is arranged to produce a delay waveform signal that is responsive to an input voltage signal. A transconductance element (118) has an input that receives the delay waveform signal and is arranged to provide an output boost current (102) that is based on the delay waveform signal and a gain of the transconductance element. A reference element (104) provides an output bias current (108) that is responsive to a static reference current (106) and the boost current (102). A bias element (110) has an input that receives the bias current (108) and is arranged to provide a bias control output (112). A power amplifier (114) is responsive to the bias control output (112) and is arranged to provide an amplified power output (RF OUT ).

Abstract: A power amplifier has power detection capabilities that include a radio frequency (RF) power amplifier that has a gain stage that includes a gain stage input, a gain stage output, and a feedback loop coupled between an input and an output of the power amplifier. A detection circuit has a first detection circuit input electrically coupled to the gain stage input and has a detection circuit output. An amplitude control circuit and a phase control circuit are electrically coupled together in series between the gain stage output and a second detection circuit input. The amplitude control circuit and the phase control circuit produce a signal that is received by the second detection circuit input so that the detection circuit can detect a signal at the detection circuit output that is proportional to a the forward power output of the power amplifier and is insensitive to power amplifier output load mismatch.
