Abstract
Power detectors for radio-frequency applications. In some embodiments, an amplifier can include an amplification stage having an input and an output, and a detector coupled to the output of the amplification stage and configured to generate an input signal representative of power associated with an amplified signal provided by the amplification stage. The detector can be further configured to generate an output signal based at least in part on 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 amplifier.
