Abstract:
In conventional optical receivers the dynamic range is obtained by using variable gain amplifiers (VGA) with a fixed trans-impedance amplifier (TIA) gain. To overcome the SNR problems inherent in conventional receivers an improved optical receiver comprises an automatic gain control loop for generating at least one gain control signal for controlling gain of both the VGA and the TIA. Ideally, both the resistance and the gain of the TIA are controlled by a gain control signal.

Claim (Index 22):
The optical receiver according to  claim 21 wherein the automatic gain control loop includes: a peak detector capable of measuring an amplitude of an output voltage signal of the VGA; and an error amplifier capable of comparing the amplitude of the output voltage signal with a reference voltage; wherein the second gain control signal is based at least in part on a comparison between the amplitude of the output voltage signal and the reference voltage.
