Design support classifier of filter circuit structure

Accompanied with recent trend of high-mix and low-volume productions, demands for performance of analog circuits used for facilities become difficult. As an advanced knowledge and know-how are needed in the design of an analog circuit, only expert designers can cope with the recent trend. In this paper, structural classifier system to support circuit design of filter circuit was proposed. This system involves three functions, optimization, classification, and retrieval of the related database which bring synergetic effects. Using these functions, a filter circuit is designed treating as a multipurpose optimization problem by GP. Efficiency improvement of the design is achieved through inferences referring similar circuit data as an external information. Each function was confirmed through a numerical experiment.
