Abstract
An optical receiver includes a photodetector coupled to a gain section having a variable gain stage. The gain stage provides an output voltage signal. A digital automatic gain control circuit is coupled to the output voltage signal and provides a digital output value to at least the variable gain stage. The gain of the variable gain stage is set according to the digital output value.
