Abstract

Differential amplifier is one of the versatile circuits in analog circuit design. In CMOS technology the differential amplifier can be realized using a NMOS or PMOS differential pair. There are several tradeoffs that determine which differential pair to be used. One criterion that is considered in making the choice is the common mode input range. This specifies that over what range of commonmode voltages the differential amplifier continues to sense and amplify the difference signal with the same gain. Moreover in order to design a versatile Op-amp amplifier its input stage must consist of rail to rail input mode range capability. The simple differential pair, either made of NMOS or PMOS, cannot meet the requirements of rail to rail common mode input. A possible solution to the problem is to use both NMOS and PMOS differential pairs simultaneously [1]. The resulting compound amplifier is called as Complementary differential amplifier. This complementary differential amplifier is used as the core element of base band amplifiers [4]. With slight modifications, this complementary differential amplifier can be used in various analog and digital CMOS circuits.

Abstract

In this paper low power CMOS Op-Amp operating with low supply voltage is described. It will begin by presenting one of the traditional low voltage CMOS Op-Amp design techniques such as folded cascode structure and then describe some more recent developments in Op-Amp design such as floating gate and bulk driven CMOS Op-Amps.

Abstract

Electronic journals have become the major source of information for any university library in order to continue the research because of various benefits over printed journals. Libraries subscribe e-journals from various publishers/ aggregators/ societies/ universities etc. and for accessing the information, users need to go on respective URLs separately. To access information from various URLs on a single platform, J-Gate is one of the service from Informatics, Bangalore (India). The present paper describes the episode of the Guru Jambheshwar University of Science & Technology, Hisar observed during the calendar year 2014. It explains the various features of J-Gate and its use by the users of the university library. The paper highlights monthly use of electronic journals from various publishers during the year 2014 and suggests the ways to improve the usage level. For Journal Finder- the database is best used in April and for Basic Search- its best use is made in December. Total 4931 hits have been observed for Basic Search and 153 hits for Advance Search.

Abstract

Electronic journals have now become the indispensable source of information for the researchers working in Research and other Institutes of Higher Learning. In the present scenario, no library can cater to the informational requirements of its users without the accessibility of electronic journals. Since the databases of electronic journals are very costly, there is need to evaluate the usage. The present study is an attempt to review the usage of Emerald databases of electronic journals. Month-wise usage of data from the year 2011 to 2015 have been compared with regard to articles downloaded. Journal of Intellectual Capital, Personnel Review, European Journal of Marketing, British Food Journal, and Employee Relations: The International Journal have been found the highly used 5 Journals. The study reports that 53781 articles have been downloaded during the spell of five years and more than 52% articles have been downloaded amongst first 32 journals. The usage is unfortunately decreased after the year 2012 and there is dire need of marketing the database and making the users aware. The suggestions for improving the usage level have been discussed.

Abstract

The aim of this paper is to establish the fixed point theorems for the special type of mappings on partial metric spaces. In this paper, the two results are proved. The first result of this paper is obtained by reducing the five constants in [19] to three constants. But second result is obtained with the help of orbital continuous maps.

Abstract

The information technologies has affected every sphere of life- personal, social and professional. The dramatical changes can be seen everywhere because of the advancement in the information and communication technologies. The services of library has incredible enhanced as the demand of users for quality information has increased manifold. The reference service is not exception of it. The digital reference service is now meeting the demands of cyber age users. The paper has defined the concept, need, essential elements and various forms of digital refence service.

Abstract

In this paper, the development of integral of a real variable is examined from the definition given by Cauchy to the definition introduced by Lebesgue. The limitations of Riemann Integral are observed. An example is also given to show then arrow class of Riemann Integral. The large class of Lebesgue Integral is also discussed.

Abstract

Emergence of information communication technology in all sectors has been changed the whole society. The primary objective of library is to cater to the informational requirements of its stakeholders in most efficient way. The digital library has shown its impact on the library services and so as the demand and quality of library services. The present paper highlights the concept, definition, characteristics and advantages of digital library. Concept, definition, levels, advantages&disadvantages of e-learning are explained. E-Learning is a valuable tool for enabling today's work forces to rapidly gain and refresh the skills and expertise they need to make businesses more competitive. At its most essential, e-learning is electronic-enabled learning, deployed across the organisations networks. It breaks the one size- fits-all training syndromes of the past by enabling "anytime, anywhere" learning tailored toward individual objectives. Role of digital libraries in enriching e-learning activities in academic institutions has also been discussed.

Abstract

The research in universities and other institutes of higher learning is available in digital format. This format is being given more importance because of reasons such- round the clock availability of information, easy to access, multimedia and multiuser access, no physical boundary, excellent searching techniques which are not available in print form etc. Efforts are being made at national and international levels to preserve the research in institutional repositories (IR). An effort made at Guru Jambheshwar University of Science & Technology, Hisar has been discussed. IR shall definitely enhance the digital and copyrighted resources of any institute. IR has been proved as a value addition and prestige of any institute. The present paper shall help the library professionals to begin to create IR.
