It features a hierarchical design style, multifunctionality, and adaption capability for its knowledge bases. The prototype called AC/DC has been realized as a set of cooperating tools for design and verification. The overall system can act like an automatic tool as well as a design assistant. In its current version it can design CMOS operational amplifiers and switched-capacitor (SC)-filters.enadaptive systemAdaptivregelungAnalogschaltunganalogue circuitExpertensystemknowledge based systemrechnerunterstützter Entwurf621conference paper
