| Abstract | In this paper, a low power, high density and fully integrated CMOS receiver front-end with digital output for optical signal processing systems is presented. The circuit is composed of transimpedance amplifier for weak optical current detection, limiting amplifier for both linear and limiting amplifications, control circuits and the digital output interface. The front-end is powered by a single 3.3V power supply with the power supply current of 12mA. Measured with a photodiode, a sensitivity of 0.7μA was achieved. The channel isolation between 8 channels is considered during the period of circuit design, layout floor plan and measurement carefully. The digital output signal is compatible with TTL/CMOS logic interface which can reduce the size of system dramatically and is easy to use. The optical sensor receiver was fabricated with a commercial mixed-signal CMOS process with feature size of 0.6μm, taking silicon area of 1.91mm×1.01mm including bonding pads for 8 channels. |

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.
