Abstract
An automatic gain control circuit for an analog to digital converter is provided. The automatic gain control circuit includes an input, coupled to an output of the analog to digital converter, to receive samples output by the analog to digital converter. The automatic gain control circuit also includes a digital to analog converter that is coupled to selectively adjust a magnitude of an input signal for the analog to digital converter. The automatic gain control circuit also includes a microcontroller. The microcontroller is coupled to the input and the digital to analog converter. The microcontroller is programmed to generate a feedback signal for the digital to analog converter to control the amplitude of the input to the analog to digital converter.
