Automated synthesis of passive filter circuits including parasitic effects by genetic programming

In this paper, we propose a genetic programing method to synthesize passive filter circuits including parasitic effects, which are very common in high-frequency application. This approach allows circuit topology and component values to be evolved simultaneously; therefore, novel circuits different from those generated by traditional methods can be explored. Experimental results show the proposed method can effectively generate not only compliant but also efficient solutions of such problems where the traditional approaches fail. q 2006 Elsevier Ltd.
