| Abstract | An improved CMOS large-signal model including the substrate/triple-well characteristics has been proposed for the application in high power-handling of CMOS RF switch circuit. In order to establish a NMOS transistor model in RF switch application, two types of test devices, series- and shunt-type NMOS transistors, have been designed and fabricated by using a standard CMOS 0.18 µm technology. Based on the measured results of insertion loss and power-handling capability, the substrate parasitic RC and pn-well junction diodes were embedded into a conventional BSIM3 model for characterizing RF small-signal and large-signal performances with zero drain/source biasing condition. The proposed model demonstrates a well prediction over a wide frequency range and a wide power operating range. The input P1dB power handling capability at 2 GHz for series-type device is about the same value of 27.5 dBm from measurement and the proposed model. With driving a negative body bias, the P1dB can be improved to 30.5 dBm. |

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.
