Abstract | Many IC applications employ both analog and digital circuits, and therefore it is desirable to integrate both analog and digital functions on the same chip (mixed signal chip). A mixed signal chip uses logic gates to perform digital signal processing while the analog cells allow the chip to interface with the analog environment. These analog cells include I/O blocks containing resistors, capacitors, reference voltage sources and comparators. Integration of all these digital and analog components on a single chip offers high packing density and low power CMOS at a lower cost. Most commonly used materials for high R value resistors are nichrome, tantalum and cermet (Cr-SiO). Extra manufacturing steps involved in depositing and patterning of these films is expensive and therefore new and innovative process for high R value resistors is needed. The authors have integrated very reliable high R value poly silicon thin film resistors at the cost of one extra masking step in a CMOS process. The authors present the results on matching, flicker noise performance and reliability of poly silicon thin film 10K resistors. Also a comparison is performed with thin film HIPO (IK) resistor |

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.
