Zusammenfassung:A nonlinear noninverting amplifier design (22) for receiving and amplifying an input signal (20) in an optical communication scheme having a nonlinear inverting feedback (32) is disclosed. The inverting feedback (32) varies nonlinearly with the input signal (20) to avoid saturation of the amplifier (22) while providing a zero state input amplitude signal to reduce the amplitude of the input signal (20) required to turn-on the feedback (32), thus allowing the amplifier (22) to operate with a wide variation of optical generators, paths, and converters. A nonlinear noninverting amplifier design (22) is provided which eliminates the need for automatic gain control circuitry and can be designed as an integrated circuit.
