| Abstract | The unlicensed band around 60GHz has been allocated for wireless communications at data rates of several gigabits per second, consequently the high speed transceivers operating at 60GHz is receiving significant research interest. This paper presents a 60GHz voltage-controlled oscillator using linear superposition technique in SMIC 0.18µm CMOS technology. This technique demonstrates the design feasibility for an oscillator whose output frequency is much higher than the device fmax. The proposed circuit consists of a quadrature voltage-controlled oscillator (QVCO) and a transconductance stage. The circuit exhibits a wide tuning range of 3.6GHz and a phase noise of −85 dBc/Hz at 1MHz offset within the entire frequency range while consuming 30.8 mW power from a 1.4V supply voltage. The output power with a 50Ω load is about −33 dBm without an output amplifier. In the real system, the output load should be replaced by 50–100fF capacitive load and the output power can reach about −20 dBm. The circuit occupies a core area of 650×700 $µm^{2}.$ |

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.
