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.

    Design of second order sigma delta modulator using preamplifier latch based comparator in 180 nm CMOS technology
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-07) Farswan, Manoj Singh; Tomar, Abhishek
    Sigma Delta Modulator (SDM) is achieving attention due to its low cost, high resolution, high signal to noise ratio etc in analog to digital converter. In SDM, the oversampling frequency is used to achieve high resolution. Also, noise shaping is inherently done to reduce noise power. The noise power in the design of SDM can be further reduced by increasing the order of the SDM. In this thesis, a second order continuous time, upto 50 kHz, SDM is designed with 1.8 V supply voltage in 180nm CMOS technology. The blocks used in SDM like integrator, subtractor and gain stages are implemented using Operational Amplifier (Op-amp) which is designed in cascade topology with miller capacitance techniques to optimize the phase margin and gain. The designed Op-amp has gain of 59.302 dB, phase margin of 59.2° and Gain Bandwidth (GBW) of 114.6 MHz. Integrator has -20 dB/decade slope for 11.12 kHz to 10.62 MHz which decides the sampling frequency of 3.2MHz. The preamplifier based latch comparator is used as a final stage of SDM. The designed preamplifier has 18.167 dB gain and 779.77 MHz 3-dB frequency which amplify low amplitude signal. The designed comparator is able to differentiate the 50uV signal and the sampling frequency is 64 MHz. The simulation is done in Cadence Virtuoso tool.With an input signal of 50 kHz and 3.2MHz clock frequency, the SNDR is 59.2 dB and power dissipation is 8.7mW of the SDM.
