Abstract | We present a novel injection locking frequency generation scheme for UWB systems. In the MBOA-UWB specification, the critical constraint on the frequency synthesizer is the band switching time (< 9.5 ns). In this paper we derive analytical expressions for the transient behavior of injection locked oscillators (ILO) and describe the design constraints on frequency settling of ILOs. We show that they are capable of UWB compliant fast frequency hopping. ILO based frequency synthesizers have a number of advantages over traditional fast hopping LO generation techniques. In particular, it eliminates the need for multiple PLLs and single-sideband (SSB) mixers reducing power consumption and eliminating parasitic spurs. |

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.
