Abstract in different language:	In this paper the theoretical basis and the algorithm of new method of electronic integrated circuit analysis and optimization in the frequency domain based on the multiparameter, large-change sensitivity conception and symbolic description of chosen two-ports have been presented. The method consists in determination increments in value of network functions caused by admittance changes of reactance elements as well as chosen two-ports, resulting from the frequency changes. The admittance two - ports, embedded in the main integrated circuit, have been divided into two groups: one - element two - ports and multi - element two - ports. For faster computer processing, the last ones have been described, symbolically. The main idea of the method proposed relies on it, that in first step the value of the network function is calculated at the first frequency, and then for every consecutive frequencies its increment, caused by admittance vector change of electronic circuit, is determined, only. It was shown, that its effectiveness is greater than traditional methods, especially in the case of circuits, in which the number of nodes of a network exceeds the number of the reactive elements as well as is growing together with the growing of number of frequency points. It was shown that numerical efficiency of this method can be speed up significantly by using special acceleration algorithm. Thanks to the symbolic description of some two-ports the effectiveness of this method has been increased considerably. Basing on this method the optimization task has been formulated and the example of optimization of integrated acoustic corrector with passive subcircuits described symbolically has been also included.
