Abstract
An optical receiver with increased dynamic range includes a photodetector, a photodetector biasing network, an amplifier and a post-distortion network. The post-distortion network compensates for gain error in the amplifier, such that a composite output voltage is relatively linear with respect to input current. The dynamic gain responses of the amplifier and the post-distortion network are equal in magnitude and opposite in phase. Additionally, a signal from at least one internal node of the amplifier may be connected to the post-distortion network, in order to further improve performance.
