| Abstract | The inherent fault-masking characteristic of the traditional loopback test produces overly pessimistic estimates of device-under-test (DUT) performance, which negatively impacts product yield, although the loopback test provides a promising low-cost test solution. The proposed method overcomes the fault-masking shortcomings of the loopback test for single-ended mixed-signal circuits by accurately characterizing the performance parameters of the individual DUTs, based on the imbalance generation technique of our previous work. Basically, the proposed method is the case study of the previous work to validate the expansibility to a single-ended circuit testing. A sinusoidal stimulus is applied to the DUT, and our loopback configuration converts the external single-ended loopback path to differential mode, in order to generate the phase imbalance between the differential pair. The imbalanced differential signals then switch back to a single-ended mode and stimulate the DUT, in order to introduce the DUT loopback responses of different weight. The nonlinear characteristic equations are then derived to characterize the individual DUT performances. Hardware measurements show that our cost-effective test approach can accurately predict DUT performance parameters. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
