Abstract:
The invention relates to a method of calibrating an envelope path and an input path of an amplification stage including an envelope tracking power supply, the method comprising: generating input signals having a known relationship for each of the input and envelope paths; and varying an amplitude and a delay of the signal in one of the envelope and input paths in order to reduce the variation in the power detected in a signal at the output of the amplification stage.
