| Abstract | This paper presents an improved PMOS-based active inductor circuit suitable for output driver in wireline link transmitters. Wider tuning range and higher inductive impedance in the desired bandwidth with respect to a previous reported topology is achieved using a varactor in the active inductor architecture and modifying the feedback resistor. Using the proposed active inductor, a prototype output driver for a wireline transmitter is designed in a 90nm CMOS technology. To model nonidealities of the active-inductor that affects the transmitter performance, an accurate large-signal, wide-band characterization technique, based on Least Square Estimation is described. Amplification of high frequency components of 10 Gb/s and 12.5 Gb/s transmitted signals over two kinds of NELCO channels using active inductors in the transmitter side, improves SNDR in the receiver side by 3 dB, as compared to the case with no inductor peaking, for the same power consumption. The transmitter circuit consumes 8.4 mW from a 1.2V power supply. |

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.
