Abstract
An optical receiver includes a photodiode, a transimpedance amplifier (TIA), a slope detection circuit, and a logic circuit. The TIA includes an output stage and a feedback amplifier and is coupled to the photodiode. The slope detection circuit is coupled to the feedback amplifier and configured to monitor a feedback signal from the feedback amplifier. The slope detection circuit is configured to provide, in response to a slope in the feedback signal being detected, a first slope-status signal indicating the slope is detected. The logic circuit is coupled to the slope detection circuit and is coupled to the output stage of the TIA. The logic circuit is configured to squelch the output stage of the TIA in response to the first slope-status signal.
