| Abstract | Low noise amplifier optimization in modern CMOS technologies is based on the noise figure minimization, preserving the input power matching. Unfortunately available analysis and design methods incorporating this design method have used very simple transistor model and are not suitable for the design in millimeter wave frequencies. In this paper we present an accurate analysis to calculate the input impedance of the inductively source-degenerated cascode LNA. Based on the analysis results we have developed analytic equations to calculate the input matching components. To compare the proposed input matching with the available ones, we have designed identical 30GHz 5mW LNA circuits, using different input matching methods. The designs have been simulated using the foundry design kit for the STMicroelectornics 90 nm CMOS process. Based on the simulation results the proposed method outperforms the available methods. Finally the circuit designed using the proposed method, has been layed out and simulated in the foundry design kit. |

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.
