| Abstract | As threshold voltage of CMOS transistors is the main parameter that takes effect from process variations, in this paper a novel method for corner detection is presented which senses the variations of fabrication process through threshold voltage of the devices. A new general purpose 2-input, 2-output, 25 rules, ANFIS based fuzzy controller is proposed to compensate the variations subsequently. In this controller novel structures are presented for each block including membership function generator, Min–Max selector and defuzzifier. As an application, bias points of comparators of a typical flash ADC are controlled through introduced system in order to compensate the process variation effects and minimizing total power consumption consequently. Due to differential structures used in the architecture of the blocks, major part of the power supply noise is rejected. The Hspice (level 49) simulation results are given using a generic 0.35 μm standard CMOS technology parameters and power supply of 3.3 V with total power consumption of 15.6 mW for 7.4 MFLIPS. Because of simple and symmetrical circuitry, layout of the proposed controller is very compact, about 410 μm × 210 μm. |

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.
