Abstract
The present disclosure provides a device and a method for adjusting envelope signals for use by an envelope tracking (ET) enabled power amplifier. The device comprises: a controller configured to calculate a difference between a first amplitude of a first envelope signal received at a first time instance and second amplitude of a second envelope signal received at a second time instance; compare the difference with a predetermined threshold; and adjust an output envelope signal corresponding to the first envelope signal in response to determining that the difference is greater than or equal to the predetermined threshold, such that the output envelope signal is adjusted step-by-step from the second envelope signal to the first envelope signal with each amplitude step being less than or equal to a predetermined amplitude step.
