| Abstract | CMOS RF ICs continue their transition from academic curiosities to practical devices. Recent milestones at the device- and building block-level include: Noise figures for single-ended LNAs of ~ldB in the low-GHz range; fully integrated oscillators with phase noise compliant with GSM specifications at under lOmW power consumption; 5GHz injection-locked frequency dividers with sub-mW power consumption and large (~30%) tuning range; MOSFET ring mixers with over lOdBm 11P3 and "zero" power consumption; shielded spiral and helical inductors with improved Q; accumulation-mode MOS varactors with Q-frequency products in excess of 100-200GHz and tuning ratios approaching 2:1; fixed lateral flux capacitors with still higher Q-f products; coplanar transmission lines with <0.3dB/mm attenuation at 50GHz; microwave-compatible ESD structures; and constant-gm biasing for process independence. These advances have combined to enable a single-chip GPS receiver in 0.5¿m to exhibit 2.8dB overall NF, 57dB SFDR at 115mW, and a 5GHz HIPERLAN receiver to exhibit 5dB NF at <45mW using a 0.25¿m technology. Scaling forces that are already firmly in place will continue to drive still greater improvements in performance. |

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.
