| Abstract | The design of reconfigurable DeltaSigma modulators requires cumbersome circuit-level simulations. Besides the challenges inherent to high-performance analog-to-digital converter (ADC) design, the gap between system-level specification and circuit-level implementation makes the design even more difficult and inefficient. Circuit macromodels are an efficient way of tackling these problems by speeding up simulation and offering insight into circuit design. This paper presents a library of structural macromodels customized for cells used in DeltaSigma modulator design. We present original structural macromodels for two operational amplifier (opamp) and one operational transconductor amplifier (OTA) circuits. These cells are used to implement the loop filter in continuous-time DeltaSigma modulators. The proposed library helps the designer capture circuit-level constrains and tradeoffs before doing circuit implementation. It also makes top-down design of analog circuits more efficient by meaningful abstracting circuit-level parameters to a higher design level |

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.
