| Abstract | In this paper, memristor emulator circuit which is built with off the shelf electronic devices is presented. It consists of three operational transconductance amplifiers (OTA) and four second generation current conveyors (CCII). Using OTA offers an extra control parameter, operational transconductance parameter (gm), in addition to frequency (f) and amplitude value of voltage across emulator (v m ). Since gm is proportional to current flowing through the bias terminal of OTA, it is possible to change the memristance variation via a simple change of amplitude value. Since gm parameter is adjustable via an external dc voltage/current source, the memristance of presented emulator circuit is electronically tuneable. Mathematical model is derived to characterize the behaviour of the emulator circuit. Frequency analysis is performed to determine how to maintain the pinched hysteresis loop at high frequencies. The presented emulator circuit is simulated with SPICE simulation program. The breadboard experiment of emulator circuit is built using CA3080 and AD844 ICs for OTA and CCII devices respectively. Frequency dependent pinched hysteresis loop in the current versus voltage plane holds up to 10 kHz. Mathematical model and theoretical analyses show a good agreement with SPICE simulation and experimental test results. |

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.
