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