| Abstract | Wide tuning range voltage-controlled oscillators (VCO) are envisioned for applications in radars, broadband communications, phase-locked loops and clock generation/distribution. In this paper, post-layout simulation results of a combined VCO with a ring quadrature VCO (QVCO), an exclusive-OR (XOR) and a fourth-harmonic summation block in 130nm SiGe BiCMOS technology are presented. The combined VCO can be tuned from 2.9 to 30.3GHz. At 2.9GHz, the VCO consumes 32.89mW of power and generates −56.5 dBm (2.24nW) of output power into a 50 Ohm load. At 30.3GHz, it consumes 34.2mW of power and generates −33.5 dBm (398nW) of output power. In both cases, the XOR consumes ∼25mW of power and the fourth-harmonic block consumes ∼5mW of power. The VCO phase noise at 10MHz offset frequency is −102.2dBc/Hz and −86.04dBc/Hz at 2.9GHz and 30.3GHz, respectively. The VCO figure of merit (FOM) is in the range of −136 to −141. The microchip area is 750µm×500µm. This VCO provides the widest tuning range in the 130nm ring VCOs reported till now. |

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.
