Abstract | This paper evaluates a novel energy efficient method of converting the time of flight of UWB radar pulses from time domain to digital domain with picosecond resolution using multiple time-voltage converters and a low power analog-digital converter. The system features single shot - multi target capability and uses only a fraction of the energy consumption of traditional highspeed ADC or counter - based solutions with much higher resolution. The method addresses a key challenge of todays UWB radar systems. The power required to convert ultra short signals from time domain to digital domain often renders UWB radars unattractive for battery powered systems like remote sensor networks. With the proposed system it is possible to overcome this limitation. Energy requirements of 0.14 nJ per range scan with a standard CMOS process are demonstrated. The results of this work are compared to state of the art solutions. |

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.
