| Abstract | In this paper, an approach towards high speed current mode based SAR ADCs is presented. The main focus is placed on the design of a unary single-sided current steering DAC working with a binary search algorithm inside the SAR loop. Reflecting the fact that current source matching and precise current settling are the most important static and dynamic properties of the current steering DAC in a current based SAR ADC, the paper contains an initial investigation of the DAC current settling when driving a linear load together with an analysis of the effects of current source mismatch and noise on the DAC performance. The theoretical analysis is compared against a schematic level implementation in a 1.2V 90nm CMOS technology. This DAC implementation is designed for an overall resolution of 10bit in the current based SAR ADC over a Nyquist band from DC to 100MHz. |

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.
