| Abstract | A symbolic macromodel for slew and settling characterization of fully differential switched-capacitor (SC) integrators is proposed in this work. This model is intended for fast behavioral simulation of data converters in the time-domain. The main advantages of the proposed model are: 1) it can be created automatically without the need of running a transient simulation; 2) it is fully composed of circuit elements that can be simulated by SPICE or MATLAB; 3) it is created in symbolic form so that adjustment of the transistor-level circuit is directly reflected in the macromodel without the need of remodeling. The proposed modeling methodology is validated by applying to SC integrators implemented by two different operational amplifiers. The step response waveforms of the integrator model have good agreement to the transistor-level simulation results with a speedup of about 20x. |

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.
