Zusammenfassung:Circuits and devices related to compensated power detectors. In some embodiments, a power amplifier can include an amplification stage configured to receive a signal at an input and provide an amplified signal at an output, and a detector coupled to the output of the amplification stage and configured to generate a slow-varying or direct-current signal as an input signal representative of power associated with the amplified signal. The detector can be further configured to generate an output signal based on the input signal and a compensation signal resulting from a combination of a first current representative of the input signal and a second current representative of an operating condition associated with the power amplifier.
