Abstract
An automatic gain control circuit includes an input gain stage for receiving and amplifying an analog input signal; an analog-to-digital converter for receiving the amplified analog input signal and providing a digital output signal; and an overload management module. The overload management module is arranged to receive the digital output signal; determine therefrom whether the received, amplified analog input signal exceeds an operating range of the analog-to-digital converter; and provide a first control signal to the input gain stage to adjust a gain of the input gain stage in response thereto.
