Abstract
Some embodiments relate to a method and circuit for gain compensation. The method includes detecting a strength of an output signal generated by a power amplifier of a transmitter in response to a commanded transmission signal. The method also includes comparing the detected strength of the output signal to a delayed version of a detected strength of the commanded transmission signal to obtain an error signal. The method further includes compensating for gain drop of the output signal by adjusting a gain of the transmitter based on the error signal.
