Abstract
An automatic gain control system () and methods thereof for a receiver for providing a wide range of continuous gain control has been discussed. The AGC includes an input stage () for providing an indication of a strength of a received signal; an attenuator stage () operable to switch a fixed amount of attenuation for the received signal; a variable attenuator () to provide a variable amount of attenuation for said received signal, and a controller () responsive to said indication for providing a variable control signal () to the variable attenuator; wherein the controller concurrently changes the variable control signal to change in the opposite direction the variable amount of attenuation by approximately the fixed amount of attenuation whenever the attenuator stage is switched, thereby extending the range of continuous gain control beyond the range of the variable attenuator.
