Abstract
A power controller for a mobile terminal variable gain amplifier (VGA). A controller consistent with the invention controls VGA output using a feedback error signal established based on the difference between a signal representative of the VGA output and a signal representative of a target output. The error signal causes convergence of the VGA output to the target output based on a magnitude of the difference. A method of controlling the output of a variable gain amplifier in a mobile terminal is also provided.
