In this paper a CMOS operational amplifier is presented. A CMOS operational amplifier is presented here which is operating at 2V power supply and 1microamp input bias current at 0.8micrometer technology using nonconventional mode of MOS transistors and whose input is dependent on bias current. The unique behavior of the MOS transistors in sub threshold region allows a designer to work at low input...
In recent days coal mining has been very dangerous activity for the workers. Who work in mine. Because of numbers of adverse effects an the environment. During mining operation dangerous gases. Like methane may be released into the air also underground mining hazards. Include suffocation, gas poisoning, roof collapse and gas explosion by keeping all those activity which done in underground coal mine...
The use of cloud computing has increased rapidly in many organizations. Cloud computing provides many benefits in terms of low cost and accessibility of data. Cloud computing has generated a lot of interest and competition in the industry and it is recognize as one of the top 10 technologies of 2010. It is an internet based service delivery model which provides internet based services, computing and...
Cloud computing is a latest and fast growing technology that offers an innovative, efficient and scalable business model for organizations to adopt various information technology resources i.e. software, hardware, network, storage, bandwidth etc. Cloud Computing is a jargon term without a commonly accepted non-ambiguous scientific or technical definition. At the foundation of cloud computing is the...
This paper describes a dynamic reconfiguration algorithm for a hybrid fiber wireless network, which takes advantage of dynamic reconfiguration in WDM based optical networks to provide bandwidth on the fly. The WDM technique for optical networks allows network operators to extend the existing capacity of passive optical networks manifolds. However presently, WDM networks were used mostly in long haul...
Ct -- This paper describes an analog-to-digital converter which combines multiple delta -- sigma modulators in parallel so that time over sampling may be reduced or even eliminated. By doubling the number of Lth-order delta -- sigma modulators, the resolution of this architecture is increased by approximately L bits. Thus, the resolution obtained by combining M delta -- sigma modulators in parallel...
