Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Performance evaluation of current mirror circuits using CNTFET
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Tomar, Anjali; Sharma, K.K.
    The current very large scale integration technology based on planar bulk MOSFETs has approached the scaling limits, particularly for analog applications, due to many challenges such as higher leakage, degradation in device matching characteristics, and less gate control over the saturation current. A promising candidate which avoids these difficulties and allows further scaling down is the carbon nano tube field effect transistor (CNTFET). Current mirror is the main building block of analog circuit designing which is used to copy the input current to many current sources. It maintains the output current constant regardless of loading. An ideal current mirror has zero input resistance and infinite output resistance. Current mirror can be used for current amplification, biasing, level shifting and active loading. In this thesis, different existing current mirror circuits have been studied and their performance has been evaluated using CNTFET. All these circuits have been simulated with the help of HSPICE simulator. 32nm CMOS technology is used for MOSFET based current mirrors and Stanford University CNTFET model is used for CNTFET based current mirrors. Simulation results of MOSFET based current mirrors are then compared with the standard results and simulation results of CNTFET based current mirrors. Parameters considered for the comparison are % error, input/output resistance, input voltage drop, bandwidth and power consumption. With the help of simulation results it is observed that CNTFET improves the % error, output impedance and bandwidth of most of the current mirrors.
