The article discusses a fast numerical algorithm for calculating the given instability of the zero level of DC amplifiers. Traditional methods for calculating the instability of nonlinear electronic circuits require multiple calculations of the stationary mode of the simulated non-linear circuit with subsequent calculation of the sensitivity of the coordinate values of work points to the variation of component parameters. Proposed method is based on the performance of a single linearization of non-linear characteristics of components only at the initial stage of solving the problem. At the subsequent stages of solving the problem, the linearized representation of components is used to calculate the given instability under the influence of external influences, as well as the technological spread of parameters during mass production of the developed circuit.
Keywords: sensitivity of work point coordinates, given instability of zero level, automation systems of schematic design, service-oriented systems.
