| Abstract | In this paper, a 100MHz low phase noise Oven Controlled Crystal Oscillators (OCXO) with the feature of lower input voltage and smaller package than mainstream products is reported. it suit for low supply voltage and miniature equipment application such as radar. Radar application VHF OCXO must own low phase noise performance, for example lower than −155dBc/Hz@1KHz when the carrier frequency is 100 megahertz. Most of the products with the same phase noise level in market have larger package and need higher supply voltage such as ( $36×27×16)mm^{3}$ and 12V input voltage. In our design A high Q factor SC cut crystal resonator is utilized in the OCXO. By optimization of the circuit structure design and sifting through the low noise components, the phase noise minus to −163dBc/Hz@1KHz while the profile of the product is decrease to ( $20×20×13)mm^{3}$ and the supply voltage is down to 5V.Thus, in some special application such as portable radar or satellite it is a available choice. Here the theoretical analysis to achieve the low phase noise in the restriction of the small package and low operation voltage is introduced and the test data is illustrated. |

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.
