| Abstract | ASTUDY of the noise characteristics of a general purpose silicon diode (type 1 N645) was made to determine whether excessive r-f noise is correlated with high failure rates. The selection of the abnormally high noise diodes was made by monitoring the noise level across the diode as it was excited with an a-c voltage within the diode maximum ratings. Mechanical stress in the form of impacts within the rated value was applied simultaneously to aggravate structural imperfections. Noise measurements at 25 mc were used for the recognition of weaknesses and early failure. The forward and reverse characteristics were obtained for the diodes exhibiting high r-f noise. These were compared with the characteristics of diodes exhibiting normal r-f noise. In the forward direction, no difference was obtained; in the reverse biased condition, the average leakage current of all the noisy diodes was considerably higher than the average of the quiet group. In addition it was noted that the r-f noise level of the diodes was almost inversely proportional to the avalanche breakdown voltage. The diodes were also tested for 1/f noise; 35% of the r-f noisy diodes also exhibited high 1/f noise, whereas only 1.2% of the diodes having normal r-f noise exhibited high I/f noise. The noise spectrum taken on a number of the silicon diodes indicates that the 1/f noise extends into the megacycle region. |

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.
