The performance of bandpass optical receivers can be improved using a lossless equalizer between the photodiode and the amplifier, as a consequence of the mismatch between the source and the input section of the amplifier. We propose two design approaches based on noise matching and on power matching, as well as a performance evaluation criterion to make comparisons between these different techniques. We have found the limit of noise performance of the approaches at a single frequency, and an upper bound, derived from the Bode-Fano limit, in a wide-band application for the power matching approach.
