Abstract | The use of CMOS Monolithic Active Pixel Sensors (MAPS) for high precision minimum ionizing particle tracking has been proven to be a viable and powerful novel experimental technique. Possible applications will strongly depend on a successful implementation of on-chip hit recognition and sparsification schemes. For this aim, a 5 bit very low power and low level signal analog to digital converter (ADC) using a double sampling switched capacitor technique has been implemented in 0.35µm CMOS technology. A non-resetting sample and hold stage is integrated. This first stage compensates both the amplifier offset effect and the input common mode voltage fluctuations. The converter is composed of three successive 1.5 bit pipeline stages followed by a 2 bit flash stage. The prototype consists of 16 ADC double-channels; each one is sampling at 50 MS/s and dissipates only 1.38 mW at 2 V supply voltage. A bias pulsing stage is integrated in the circuit. Therefore, the analog part is switched OFF or ON in less than 1 µs. The size of the ADC is 80 µm × 1.4 mm. This corresponds to the pitch of 4 pixel columns in which each one is 20 µm wide and can be easily integrated in the MAPS. |

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.
