| Abstract | In this paper we present a low power interface circuit with the new approach of current mode successive approximation (SAR) ADC for biomedical implantable devices application. The circuit includes band pass filter, Gm and current mode SAR ADC. The SAR ADC is a low power circuit that is composed of current mode S/H, current mode comparator, current mode DAC and conventional logic. In this circuit the signal input range is between 0–5mV and the acceptable signal frequency range is from 0.1Hz to 500Hz. The resolution of the current mode SAR ADC is 8 bit with the LSB of 500pA. The circuit is simulated in a 0.18µm CMOS technology using supply voltage of 1.8V. At the sampling frequency of 40Ks/S the total power consumption is 2.2µW. |

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.
