    Design of low power inverter based OTA in FinFET technology
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-02) Mohit Kumar; Sharma, K.K.
    OTA performance analysed by following four different analysis on SPICE tool First DC analysis of proposed circuit is done on input sweep from -0.7 to 0.7 to understand the output current behaviour and finding proper operating point. The following parameter has been calculated as – Output current swing from -125μV to 125μV, differential mode transconductance 215.29 μS at IDS = 23 μA and total power consumption at Z=50Ω is 234μW. VG1 and VG4 terminal voltage can be used to tune the transconducatance value. There is no need of extra regulated on chip supply voltage. Second, Frequency response analysis is performed to calculate differential mode gain , common mode gain, unity gain bandwidth, phase margin, CMRR, PSRR. Achieved open loop gain of the circuit is 52dB , unity gain bandwidth is 1Ghz at CL = 0.1pF , phase margin is 80˚,PSRR+ obtained 52.007dB, PSRR- obtained 52.012dB, CMRR obtained 49.5dB. Positive slew rate and negative slew rate values are 1.034 v/ns and 0.83 v/ns respectively In proposed circuit noise analysis has been done at load Z=50Ω. Proposed circuit suffer with total input noise value of 1.08μV/√Hz and total output noise calculated to be 6.43nV/√Hz .

    Planning and designing of rainwater harvesting system in Graphic Era Hill University, Bhimtal
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Mohit Kumar; Pravendra Kumar
    Water is the most precious natural resource and a universal asset. With the increasing population and global change, rainwater conservation have become worldwide focal issues, particularly in the water stressed regions. Rainwater harvesting, based on the collection and storage of rainfall, has been widely used for domestic use and agricultural production in hilly areas. It has advantages of simple operation, high adaption, low cost and maintenance. The present study was conducted at Graphic Era Hill University, Bhimtal, Uttarakhand, keeping in view the importance of rainwater harvesting. The rainwater was harvested from roofs of the hostel, canteen and surrounding land surface area. The rainfall data of last 40 years was analyzed to determine the probability of occurrence. The optimum size of the tank is selected based on the water budgeting analysis of average monthly rainfall data. The results show that rectangular R.C.C. tank of sizes 55.62 m3 for boys hostel, 34.83 m3 for new boys and girls hostels and 122.36 m3 for happy zone are suitable on the basis of demand and availability of water. The cost of construction of tank of size 55.62 m3 for boys hostel is Rs 155035.98, of size 34.83 m3 for new boys and girls hostels is Rs 129901.13 and of size 122.36 m3 for happy zone (canteen) is Rs 295610.82 and for recharge pit is Rs 514877.6. The annual availability of water through roof-top water harvesting is 20703.23 m3, out of which 13350 m3 is used for domestic purpose and 17857.46 m3 is used for ground water recharge. The total cost of the system is Rs 4963853.93 which includes cost of guttering, conveyance, distribution of water and maintenance of the system till the end of the life of system (25 years). The B-C ratio and Pay-back period for harvesting systems of boys hostel, new boys and girls hostels, and both for hostels and canteen are found to be 0.96, 3.16 and 1.8, and 25 years, 7.88 years and 13.20 years, respectively.

    Response of organic manures on growth, yield, quality and shelf life of mango (Mangifera indica L.) cv. dashehari
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2010-07) Mohit Kumar; Singh, C.P.
    The experiment was conducted at Horticulture Research Centre, Patherchatta, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during the years 2007-08 and 2008-09. The experiment was conducted on 18 years old mango trees of cv. Dashehari consisting of thirteen treatments in ‘Randomized Block Design’ with three replications. The total number of trees included in the experiment was 39. All the selected trees were almost uniform in growth and vigour. The trees were given uniform cultural operations during the course of investigation. All treatments were applied on 15 December 2007 and 2008. Full dose of farm yard manure, vermicompost, poultry manure and neem cake were applied as basal. No manure was applied to the control. Maximum tree height was observed with the application of 25 kg poultry manure per tree during both the years. Tree spread, shoot length, number of fruits per tree and fruit yield per tree was maximum with the application of 75 kg vermicompost per tree during both the years. Physical characteristics like fruit weight, fruit volume, fruit length, fruit breadth, pulp weight, peel weight and stone:pulp:peel ratio of fruit was found maximum in 75 kg poultry manure per tree during both the years. Maximum TSS, titrable acidity, ascorbic acid, TSS: acid ratio and total sugars of fruits was observed with application of 75 kg vermicompost per tree during both the years. Increase in TSS, total sugars, reducing sugars, non-reducing sugars and?-Carotene contents from the day of harvest to 6 days of storage than it declined under all the treatments during both the years. The maximum TSS, titrable acidity and ascorbic acid content was recorded from the day of harvest to 8 days of storage with application of 75 kg vermicompost per tree during both the years. The maximum total sugars content, reducing sugars and non-reducing sugars content from the 2 days of storage to 8 days of storage was found maximum in 75 kg poultry manure per tree during both the years. Maximum N content of the leaves was found with application of 30 kg neem cake per tree, while, leaf P and K content were found with application of 75 kg poultry manure per tree in the year 2007-08 and 2008-09.The application of different organic manures on mango trees cv. Dashehari is useful for improving the growth characteristics, flowering characteristics, fruiting characteristics, quality characteristics and shelf life of fruits.
