Abstract We present algorithms for reducing large circuits, described at SPICE-level detail, to much smaller ones with similar input-output behavior. A key feature of our method, called time-varying Pade (TVP), is that it is capable of reducing time-varying linear systems. This enables it to capture frequency-translation and sampling behavior, important in communication subsystems such as mixers and switched-capacitor filters, Krylov-subspace methods are employed in the model reduction process. The macromodels can be generated in SPICE-like or AHDL format, and can be used in both time- and frequency-domain verification tools. We present applications to wireless subsystems, obtaining size reductions and evaluation speedups of orders of magnitude with insignificant loss of accuracy. Extensions of TVP to nonlinear terms and cyclostationary noise are also outlined.

About National Digital Library of India (NDLI)
NDLI logo

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.
