| Abstract | Random Number Generators (RNGs) constitute the essential foundation of many applications, e.g., cryptographic technology, and statistic based computing. The vast majority of RNG proposals, generate binary sequences with uncorrelated and equiprobable bits. However, in certain applications, such as stochastic computing, the binary sequence is required to be generated not with 0.5 logic “1” probability, but with a custom specified one. This paper presents a probability modulated True Random Number Generator (TRNG), that produces binary sequences with a desired probability of logic “1”, according to a value resident in a register. The proposed circuit relies on the thermal noise as random signal source and it was implemented in 65nm CMOS technology. Simulation results reveal a quasi-linear dependence, between the output logic “1” probability sampled at 1GHz, and the modulating voltage (obtained from the register value by mean of a D/A converter) over a range of 20mV. For a desired probability of 0.5, the sequences randomness was validated by the NIST tests. |

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.
