| Abstract | This paper describes a 440-nA true random number (RN) generator for passive ultrahigh frequency radio frequency identification (RFID) tags that operate in the 900-MHz band. Since passive tags derive their power supply through the rectification of the incoming RF signal, limited power is available, and hence, a typical total IC current budget is less than a few microamperes. An RN is generated by a passive RFID tag on the fly, and it is used by the reader to identify the tag uniquely and communicate with it in a field consisting of many tags. The RN in this paper consists of a 16-bit-long deterministic binary sequence to which a 3-bit true RN is added. Without the 3-bit true RN, if two tags happen to have the same deterministic 16-bit sequence, a collision occurs, and there is no way to resolve it. In this paper, we propose a power efficient way of generating the 3-bit true RN using the jitter-sampled carrier technique. This technique subsamples the already present 900-MHz RF carrier using a jittered (noisy) clock. The design challenges of sampling a high-frequency signal that swings above and below ground are described. In addition, the generation of a jitter of adequate magnitude with adequate high-frequency spectral content to ensure that the number is truly random is also described. Measurement results on a silicon prototype implemented in a 130-nm analog CMOS process are provided. |

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.
