Abstract The paper presents experimental study of the major erbium-doped fibre amplifier (EDFA) features such as gain at low signal and gain saturation by an application of different erbium-doped optical fibres (EDFs). The main objective of the research is to estimate how the performance of EDFA varies depending on the length of doped fibre, pumping configuration scheme, as well as excitation source power. It is shown that a high gain coefficient of 16–20 dB can be practically achieved.

The feature of implementing of loops with self-compensation of CMOS transistors differential resistance in the gain stages is reviewed. Shown that these compensation loops reduce the parametric sensitivity of the stage and the transistors output capacitance influence on a range of operating frequencies. А set of loops of cancellation of the CMOS transistors parasitic parameters influence on stage cutoff frequency was proposed. The conclusions were made. An example of cost-stage high gain was given.
