In this paper, we consider the problem of development of equivalent circuit of non-linear element with the current-voltage characteristic controlled either voltage or current, which can be modeled without any changes of scheme in accordance with design requirements. For solving the problem we use an analog-digital-analog element. The current-voltage characteristic of this element is determined by the program of the digital device work. To approximate the characteristics of non-linear elements we apply polynomials of varying degrees - segments of the Taylor series, Maclaurin, Lagrange, et al. In our opinion, the solution of such a problem is relevant.
