| Abstract | In this paper Geometric Programming is successfully applied to the power optimization of CMOS operational amplifiers using a model valid in all regions of inversion (weak, moderate and strong), which assures a true globally optimal design. A complete transistor model presents some problems on the formulation of the Geometric Program. We will show in this paper that in the case of power optimization, a careful analysis of the physical meaning of the conflicting model equations, allow us to overcome these problems in a simple and efficient way. The proposed algorithm is tested in several cases for a Miller amplifier, showing how the optimum inversion level spans all the inversion regions as the target bandwidth changes. |

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.
