| Abstract | In this paper, a 12-bit high resolution, power and area economy Digital Pulse Width Modulator (DPWM) with process and temperature calibration is proposed for digital controlled DC-DC converter. It adopts the differential delay cell so as the size is minimized compared to the single ended one. Voltage controlled inverter is built to be a deferential delay cell. Both the delay cell is optimized and the additional control node makes the calibration possible. The process and temperature monitors provides the desired feature aimed to calibrate the frequency variation caused by the process corner and temperature factors, which allows this delay line can be served as a clock. The lookup table combines different situation and output proper control voltage to the delay cell. Each module is verified by simulation and whole block is working properly under different corner using 0.18um technology. |

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.
