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 10):
An optical receiver comprising:\n a photodetector for converting an input optical signal into an input electrical current signal; a transimpedance amplifier (TIA) for converting the input electrical current signal into an input voltage signal, the TIA including a feedback resistor R F  and a variable gain feed-forward amplifier for generating a feed forward gain A o ; a gain amplifier for amplifying the input voltage signal to a desired voltage level; and an automatic gain control loop for generating at least one gain control signal capable of varying the value of the feedback resistor R F  and the feed forward gain A o  of the variable gain feed-forward amplifier.
