| Abstract | This paper addresses voltage boosters for on-chip solar cells on a standard 0.18 μm CMOS technology. Voltage boosters, also referred to as DC/DC converters or charge pumps, are needed to make the open voltage of micro solar cells compatible with the power supply of current standard CMOS technologies. This paper is oriented to on-chip solar cells for focal-plane processors, where the photodiode array can be configured along time for both image acquisition and energy harvesting. The large area occupied by the focal-plane processor itself constrains the design of the charge pumps, as there is small room for them, forcing the use of relatively small capacitors too. This paper assesses the main performance metrics through electrical simulations of three charge pumps, namely, the Dickson, the Fibonacci and the heap charge pump. The paper has a clear practical orientation, outlining how to configure the photodiode array of a focal-plane processor along time to increase the power efficiency. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
