Title:
OPTICAL RECEIVER WITH INCREASED DYNAMIC RANGE
Document Type and Number:
WIPO Patent Application WO2006020695
Kind Code:
A3
Abstract:
An optical receiver (60) with increased dynamic range includes a photodetector (62), a photodetector biasing network (64), an amplifier (66) and a post-distortion network (68). The post-distortion network (68) compensates for gain error in the amplifier (66), such that a composite output voltage is relatively linear with respect to input current. The dynamic gain responses of the amplifier (66) and the post-distortion network (68) 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.
