Abstract
A receiver gain tracking loop utilizing two Digital-to-Analog Converters (DACs) and methods for operating the gain tracking loop are provided. The gain tracking circuit includes a signal detector for detecting at least one signal and outputting a detected signal; a digital integrator connected in series to the signal detector for integrating the detected signal in the digital domain; two DACs connected in parallel to the digital integrator; and an analog summing element for summing the first digital output and the second digital output of the DACs producing a combined output.
