1. An arrangement comprising:
one or more amplifiers configured, during operation of the arrangement, to provide a first signal; a detector operatively coupled to the first signal and configured, during operation of the arrangement, to detect an envelope of a coupled signal to produce an envelope signal; a filter operatively connected to the detector and configured, during operation of the arrangement, to filter the envelope signal to produce an average power signal that corresponds to an average power of the coupled signal; a subtractor operatively connected to the detector and the filter and configured, during operation of the arrangement, to produce a difference signal that corresponds to the difference between the envelope signal and the average power signal; and a circuital arrangement operatively connected to the subtractor and configured, during operation of the arrangement, to adjust one or more parameters of the one or more amplifiers based on the difference signal. |
