AN APPROACH TO AUTOMATIC CIRCUIT DESIGN USING GENERAL- PURPOSE CIRCUIT SIMULATORS

In this work an approach to automated design of the analog circuits is developed using the standard circuit simulator OrCAD PSpice. The realization of this approach is based on the principles of analog behavioral modeling. The input data, the design conditions and limi-tations are described using the possibilities of the Spice input language, which allows the in-clusion of the complex functional dependencies between the design quantities. The different design stages are presented using the corresponding modules: calculation of the nonlinear distortion coefficient and the standard value determination of a capacitor. These modules are realized by autonomous computer modules and can be used in different design procedures
