| Abstract | In this paper, LED driver and optical receiver for 650-nm plastic optical fiber (POF) applications are designed and implemented using 0.5-µm CMOS technology. In LED driver, modulation current has to be arranged in 3 to 4-mA to meet eye protection regulations in visible red wavelength (650-nm). To apply for low cost POF applications, simple and low cost LED driver is proposed. LED driver is designed to operate at 50-Mb/s bit rates and consumes only 6-mA DC currents including modulation current of 3.5-mA. In the receiver side, two methods of auto-threshold control technique will be introduced and compared. The designed optical receiver achieves transimpedance gain of 145-dBΩ, 50-Mb/s operations with 45-MHz bandwidth for 4-pF photodiode parasitic capacitance. And proposed optical receiver guarantees digital level output swing against the range of incident photo current from 200-nA to 25-uA and the range of operating frequency from DC to 50-Mb/s. Receiver chipset consumes only 10-mW from a 3.3-V single supply. |

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.
