| Abstract | Symbolically generated network functions for an analog integrated circuit are complicated in general. For this reason a variety of simplification methods have been proposed in the literature. In this work a novel topology-based symbolic simplification method is proposed, which is capable of generating a simplified symbolic network function together with a simplified small-signal circuit. The technique is developed by applying the recently proposed graph-pair decision diagram (GPDD) algorithm that generates a symbolic network function stored in a binary decision diagram (BDD). Two types of element elimination can directly be operated on such a GPDD data structure. The performance variation by eliminating each symbol from the original circuit is assessed by the means of two monitored response metrics (dc gain and phase margin). After sorting the performance loss, those circuit elements with less performance loss are eliminated, resulting in a reduced GPDD which is automatically a simplified network function. A simplified small-signal circuit is available simultaneously after reduction. Applications to two operational amplifier examples confirm the effectiveness of the proposed methodology. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
