The purpose and problems of this work consist in research of schemes analog and the discrete and analog reconstructed integrators, feature of their construction and work, determination of uniqueness of each scheme, both on circuitry execution, and on a way of reorganization, carrying out the analysis. For the solution of a task the analysis of domestic and foreign works is made, schemes analog are constructed and the discrete and analog reconstructed integrators, work has survey character. During the comparative analysis, in article, it was revealed that depending on the specific solved objective, and also from technology of production, any of circuitry solutions of integrators can appear more effective in comparison with others.
