In this work a new method of linear circuit design in frequency domain by poles (zeros) distribution optimization is presented. The method which uses the relationship between poles and appropriate sums of circuit time-constants does not need the poles determination, explicitly. In the first stage of the method the criterion function is generated in semi-symbolic form, while in the second stage the optimization process is performed. The optimization loop does not include circuit equations formulation and solution. Thanks to this fact the method proposed appears to be very efficient. The example for optimal capacitors choice in such a way to reach the required transfer characteristics has been also included.
