| Abstract | We report here the results of some laboratory experiments performed to validate the effectiveness of a technique for the self tuning of integrated continuous-time, high-speed active filters. The tuning algorithm is based on the application of a pseudo-random input sequence of rectangular pulses to the device to be tuned and on the evaluation of a few samples of the input-output cross-correlation function which constitute the filter signature. The key advantages of this technique are the ease of the input test pattern generation and the simplicity of the output circuitry which consists of a digital cross-correlator. The technique allows to achieve a tuning error mainly dominated by the value of the elementary capacitors employed in the tuning circuitry. The time required to perform the tuning is kept within a few microseconds. This appears particularly interesting for applications to telecommunication multi-standard terminals. The experiments regarding the application of the proposed tuning algorithm to a baseband multi-standard filter confirm most of the simulation results and show the robustness of the technique against practical operating conditions and noise. |

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.
