| Abstract | This paper presents the performance optimization of a UHF Dickson voltage-multiplier used for Radio-Frequency Energy Harvesting in 130 nm CMOS technology. The main axis of intervention is the strong reduction of parasitic capacitance with layout modifications. An improvement of existing pads is proposed in order to reduce the capacitive coupling. A novel Schottky diode is proposed as well. The latter is characterized by low area occupation and low parasitic capacitance without compromising forward current capabilities. A complete electrical characterization of the new device is included. Time and cost constraints prevented major manufacturing modifications (ex. technology node, circuit topology) yet a remarkable gain in performance is demonstrated. On-wafer measures of a 3-cells Dickson voltage-multiplier RF/DC efficiency will highlight the improvements. |

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.
