| Abstract | In this paper we present a power management and a clock generator for a novel passive UWB tag. It can be used in many applications such as radio frequency Identification (RFID), and ubiquitous wireless sensing. As same as conventional RFID, the tag captures the power from the incoming RF signal, converts to DC and stores it in a relatively big capacitor. A voltage sensor and a regulator provide stable voltage for the whole circuitry during operation mode. A clock circuitry generates a low jitter and low skew clock for ultra wideband transmitter to transmit data. In such passive system the power consumption of each block should be as low as possible. On the other hand, performance degradation across process, voltage, and temperature variation (PVT) is another problematic challenge in low power and low cost circuit implementation. In this work, the power management unit including of an RF power scavenging, a voltage sensor, a low drop out regulator and a clock generator are designed and their performance across PVT variation are analyzed. The module is designed and is fabricated in CMOS 0.18 mum technology. |

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.
