Nanotech – Future Applications of Graphene: Video

Great Things from Small Things .. Nanotechnology Innovation

4 DisruptiveSamsung Advanced Institute of Technology, the core R&D incubator for Samsung Electronics, has developed a new transistor structure utilizing graphene, touted as the “miracle material.”

As published online in the journal Science on Thursday, 17th May, this research is regarded to have brought us one step closer to the development of transistors that can overcome the limits of conventional silicon.

Currently, semiconductor devices consist of billions of silicon transistors. To increase the performance of semiconductors (the speed of devices), the options have to been to either reduce the size of individual transistors to shorten the traveling distance of electrons, or to use a material with higher electron mobility which allows for faster electron velocity. For the past 40 years, the industry has been increasing performance by reducing size. However, experts believe we are now nearing the potential limits of scaling down.

Since graphene possesses electron mobility about 200 times greater…

websites which provide vast number of free ebooks

hi friends here u can find almost every book related to vlsi or any other branches

1)http://libgen.org

Here you have to enter exact name in the “book search” field(if search name is mixed,it gives zero results )

this is the great site  and hope it never disappoints you

2)http://en.bookos.org

not as the best as “libgen” but you can get good books

3)http://en.bookfi.org

4)http://libgen.net

And here we have two best sites for scientific articles

1)http://libgen.org(provided exact name of the scientific article in the “search scientific article ” field)

2)http://en.booksc.org

Here are some more interview questions asked in cosmic circuits… These are also analog questions only

Guys these are all seems bit difficult at first… but if u keep on practicing, they will never be new to u guys… so practice practice practice…

1)COSMIC CIRCUITS

2)COSMIC CIRCUITS with Solutions

analog interview questions

analog_guide_RajaReddy

To solve the questions listed in the above document… it is suggested that u should solve the analog ic design by razavi book back side problems…. otherwise it would be a bit difficult….

suggestions for those who are appearing for digital and analog interviews….

Hi friends by now u might have faced some interviews… the feedback i got from my friends is…

those who are placed are strong at basics like deference bn combinatorial and sequential logic, use of gray code,dfrnce bn blocking and non blocking statements in verilog,dfrnc bn signal and variable,and some basic c language questions..,..etc… i posted many of these kinda questions… Iam here not to test ur abilities i jus want u to know the concepts and dfrnt kinda questions u may face… soon i will post feed backs from our seniors which would be much usefull…

=>a small and good suggestion for u guys, I think u guys know http://www.edaboard.com   very well

and there are dfrnt sections like

basic electronics questions ,asic questions,analog questions, dsp questions …,,,..etc

And each section consists over 20000 questions ,ofcourse some are junk questions but if really have the patience(patience is a virtue), go through these… u will find brilliant questions… which are upto date questions… it is of so much useful..TO GET STRONG BASICS IN DIGITAL

1) STUDY THE DIGITAL DESIGN By MORIS MANO FULLY

2) SOLVE GATE DIGITAL QUESTIONS FULLY(When it comes to the interview point, u should be handy in solving… So practice practice practice)I think all u have gate materials

3) SOLVE IES PREVIOUS DIGITAL QUESTIONS FULLY

4) U SHOULD KNOW ANY ONE OF THE HARDWARE LAUNGAGE LIKE VHDL,VERILOG(verilog more preferred)prefer verilog

5) DONT FORGET ABOUT C LANGUAGE…it hunts u everywhere..:)

6) I THINK U NEVER FORGET RABEY BOOK( 5th Chapter,timing equations etc.,.)set up and hold times,a must questions in every interview

7) KEEP SURFING ON THE NET FOR ANY UPDATED QUESTIONS.,.

8)AND SOME COMPUTER ORGANISATION BASICS LIKE CACHE MEMORY,TYPES OF CACHE, FIFO DEPTH..

TO GET STRONG BASICS IN ANALOG

1)ESPECIALLY FOR US(VLSI) RAZAVI BOOK PRESCRIBED BY KP SIR AND SOME CONCEPTS OF KEN MARTIN AND ALLEN GIEGER

2)A STRONG SUGGESTION FROM OUR SUPER SENIORS IS PRACTICE RAZAVI BOOK PROBLEMS WHICH ARE AT THE END OF EVERY CHAPTER.,. I HAVE SOLUTION MANUAL FOR EVRY RAZAVI PROBLEM IF U WANT JUST MAIL TO I WILL SEND THE LINK..

3)SOLVE GATE AND IES PREVIOUS ANALOG QUESTIONS FULLY

4)The main concepts u need to go through are listed here http://www.learnanalog.com

5)ANOTHER BOOK IS FUNDAMENTALS OF MICRO ELECTRONICS BY RAZAVI(BASIC BOOK)..

After reading this book  will easily understand analog ic design by razavi.,..

So what are u looking at just go and practice

And here are more questions….. have fun with these …:)
