Abstract | In this paper, the performance of asymmetric self-cascode (A-SC) fully depleted silicon-on-insulator n-channel metal–oxide–semiconductor field-effect transistors configuration applied to common-source current mirrors (CMs) have been analysed through experimental measurements, comparing with symmetric self-cascode configuration as well as with standard uniformly doped transistor. The mirroring precision, output resistance and output swing have been used as figures of merit to evaluate the improvements achieved with the use of A-SC transistors. Two-dimensional numerical simulations have been also performed in order to further explore the advantages of A-SC transistor in common-source CMs. The obtained results have shown that the best mirroring precision has been obtained with larger channel lengths of the transistor near the source. Despite the worsened intrinsic mismatching presented by common-source CMs implemented with A-SC transistors in comparison with single transistor CM, the A-SC structure has allowed larger output resistance, breakdown voltage and better mirroring precision. |

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.
