Abstract
An automatic gain controller for a receiver analog frontend is provided. The automatic gain controller sets a plurality of gains for a plurality of analog frontend stages, respectively. The automatic gain controller detects a first signal level at an output of the analog frontend, determines that the first signal level is saturated and sets a first gain of a first analog frontend stage of the plurality of analog frontend stages to a first coarse gain value based on the first signal level. In response to setting the first gain, the automatic gain controller detects a second signal level at the output of the analog frontend, determines whether the second signal level is saturated and on a condition that the second signal level is not saturated, sets the first gain of the first analog frontend stage to a first fine gain value based on the second signal level.
