Recently, telecommunication system requires high performance, low noise, low power and high linear RF circuits. Since the digital modulation design requires highly linear front end circuits, the linearity requirement of the LNA becomes more rigorous. Due to possible large interference signal tones at the receiver end along with the carrier, LNA is expected to provide high linearity, thus preventing the intermodulation tones created by the interference signal from corrupting the carrier signal. The research focuses on designing a LNA which achieves high linearity without sacrificing any of its...

In recent years, down scaling in CMOS advanced technologies has provided high performance in the digital circuits and reduced cost thereby meeting to a large extent the increasing demand of wireless communication products. With this technology advancement, the unity-current gain frequency of CMOS technology is now over several tens of GHz making the realization of system on-chip solution possible which turns to further reduced cost. The concept of the RFIC design needed for the design of low noise amplifier such as gain, noise, stability, linearity, power consumption etc is discussed in the...

The concept of the RFIC design needed for the design of low noise amplifier such as gain, noise, stability, linearity, power consumption etc is discussed in the report. An overview has been given on different LNA architecture, their advantages and disadvantages have also been discussed.In this thesis the design and analysis of a low noise amplifier at 2.4GHz frequency has been discussed. We used cascode source degeneration topology for this design because this is provides some significant advantages over other topologies. The designed circuit is simulated with the help of spectre simulator...

This study is based on design and implementation of a 16 bit Arithmetic module, which uses Vedic Mathematics algorithms.The Arithmetic module has been designed which employs these Vedic multiplier and MAC units for its operation. Logic verification of these modules has been done by using Modelsim 6.5. Further, the whole design of Arithmetic module has been realised on Xilinx Spartan 3E tools. The synthesis results show that the computation time for calculating the product of 16x16 bits is 10.148 ns, while for the MAC operation is 11.151 ns. The maximum combinational delay for the Arithmetic...

Indian short nosed fruit bat, Cynopterus sphinx, is one of the common fruit bat among Pteropodidae family, which is commonly distributed throughout Indian subcontinent. Cynopterus sphinx is having some unique morphological characteristics such as dog shaped head, divergent nostril, large, prominent eyes and short ears with white margin. In males, the chin, anterior part of the shoulder, sides of the chest, belly and thighs are characteristically orange tinted. In females, the color is usually tawny brown; the rump is gray brown with paler gray belly. Both the first and second fingers have...

Coriandrum sativum L. is an annual herbaceous plant extensively grown and it's contributed 70% of the total seed spices in India. Coriandrum sativum leaves are used in preparing chutneys, sauces and flavouring in curries and soups. The seeds are used as spices in the preparation of curry powder, pickling spices, condiment and medicine. Its oil is used as a valuable ingredient in perfumes and food industries. Apart from it is also used for flavouring pastry, cookies-cakes, tobacco, bakery products, meat, fish, soda, syrups, candy preserves and liquor. Experimental finding indicates that high...

The Indian subcontinent has a rich diversity of chiropteran fauna and a few studies have been conducted on the diversity of Indian chiropteran fauna. So the objectives were taken to access the diversity of chiropteran fauna, roost selection and create awareness among people on bat conservation in Uttar Pradesh. During the field survey, a total of eleven species of bats were observed and three of them are frugivorous bats, such as Pteropus giganteus, Rousettus leschenaulti and Cynopterus sphinx (Pteropodidae). Pteropodid bats prefer to roost on large trees, leaf fronts, twigs and modified...
