My Experience with Analog Devices
20-08-07 NIT Bhopal.
Executives from Analog Devices, Banglore were expected to start the campus recruitment process at 10:30 am so I reached the porch of college at exact time. But after reaching I came to know that the team from AD has not arrived yet and it is postponed to 2:00 pm. Today only our minor exam for VII semester has been started. Due to the time shifting of AD the TPO people has changed our exam timing to 12:45 pm, which was supposed to start from 3:00 pm. That means we got 2 more hours to prepare for Industrial management, which I have studied a little due to preparation for AD.
I finished my minor exam at around 1:45 pm and we all students eligible for AD written rushed to the conference room of TPO. The eligibility criteria were cgpa 7.5 and ECE, EEE and ICE were allowed to seat. As we all took our seat the executives started with presentation intimating us with what exactly AD is and why people are going crazy about it. They have given detail of what all fields they are working and what is the prospect working at AD, Banglore. RAY STATA started AD in 1965. They mainly work in DSP domain (Blackfin processor, SHARC processor), IC design and software for their product. About AD Hyderbad they mainly work in wireless modules and MEMs. The SHARC processor is full made in AD Banglore and it’s their copyright so this shows that AD Banglore has a unique position among all other branches all over world. The package was 5.66lac per annum with 4.5lac in hand, estimated benefits of 1lac and estimated profit sharing of 16k. This was pretty good amount for fresher that’s what I felt. After the ppt round we were called for written test that comprises of technical paper of 1:30hr and aptitude of 45 minutes. I have appeared for it but I couldn’t clear the written test so I don’t have any further information regarding interviews. I just know that there will be 3 technical interviews and at last 1 HR round.
The technical written paper is bit tough. I am including whatever I remember.
1) How many 3 input AND gates are required to make N input AND gate?
2) If a car has a battery of 12 V and 5A current and if one of application requires double the voltage and current then configure the batteries for the required application?
3) A circuit was given with a capacitor fully charged to voltage 5V at t=0. There were some registers and capacitors in the circuit and one switch. There was no power supply. If the switch is closed the find the current through each resistor at t=0. Find the current at saturation and find the voltage across each capacitor at saturation. (Refer van vulkenburg or Electric networks by Chakroborty).
4) A system has an input (IN) bit string, which is synchronous with CLK, and the output is ‘1’ only when there is odd number of 1s in last three bits received. Now make a sequential circuit using D flipflop as a sequential element and any number of gates can be used for combinational circuit. (Assume there is no RESET pin in flipflop).
5) There was a question on superposition theorem. An analog circuit was given with two-power source you have to find the output voltage V0.
6) A question on current mirror circuit was given and asked to find the voltage across one resistor.
7) A question on delay in sequential circuit was given. The value of propagation delay and delay on wire was also given. They asked to find the maximum frequency at which the circuit can work.
8) A data sheet of IC 7400 was given. The value of Vih, Voh, Vil, Vol, Iil, Iol, Iih, Ioh was given. They asked to find the fan out of each gate of IC and also the effect of some noise voltage on the output.
9) Question on propagation delay was asked.
The aptitude section contained 3 groups of questions with different marks. There were total of 10 questions. The aptitude questions were bit tough for me and they were very easy of all who are preparing for CAT. They knew all questions as all came from some previous CAT question. So to get through AD aptitude you must work on your aptitude skills.
Prepare well for DSP, IC and Digital design and aptitude questions from CAT syllabus.
Wish you all the best.

Trip to bhimbethika...&...Bhojpur...!!!
15th aug,07..yes the 60th independent day of India...we the team of Vision decided to celebrate this day by visiting Bhimbethika and Bhojpur and in evening we had a dinner party.
Bhimbethika, as the name suggest, has a very mythological importance from the day of Mahabharata. Bhim, the giant muscular among Pandava has taken rest in that holy place during their days in forest. Today we can see various paintings drawn on the walls of caves in Bhimbethika. That shows the ancient culture in this part of india.
We reached there in a bus all singing and dancing. During our return, we had a small picnic on the edge of a river near the place.
After that we went to Bhojpur, where we worshiped The Shiva and enjoyed the water play...
At our return we went to a dhaba where we final year treated all our juniors for out placement party....
It was a very happening and enjoying experience for me...

VISION has organised a seminar on Basic Electronics
I haven't mentioned much abut myself...Let me start with VISION. It is the only technical society in MANIT run by the students.The head of this society is Miss Roshni Kumari a final year Civil Engg. student. I have been working in this club from my 6th sem. and now i am Technical co-ordinator. I got interested in this society because I found it is organising lectures and seminars on very relevant technical topics and the information is given by students to the students. I found it a very good way of sharing knowledge and so I am working here very actively.
Today we have organised a lecture and project demonstartion session on Basic Electronics. The main moto of this 2hr session was to intimate the first yr and second yr students of various branches in MANIT with all basic components in Electronics Lab which they are either working on or going to work on. We started with the BREADBOARD..how to use it...how rows and columns are interconnected...how to put ICs on it...and all FAQs of using breadboard...we have given a huge importance to breadboard 'coz we found that all the studenst are always making mistake in connections with breadboard which led to failure in ckts and damaging of ICs.
After that we gave detail information abut Resistor, capacitor and inductor...the three pillar of any ckt design. We included the COLOR CODING of resistor, what 103 represents in capacitor reading??...which capacitor(Electrolytic or ceramics) and when??...how to determine inductance from its geometry...and their uses...Then we moved towards using Multimeter and powersupply...we have taught them to generate both positive and negative voltage from two power supply which is always needed for Opams operation. LED,IR and Zener diodes are included in presentation..At the end of lecture session we have included Regulator,OPAMS,DIGITAL IC,TIMER ,Microcontroller and SENSORS... It gave them a good overview of all the basic components used while working on any ckts.
A short lecture was also taken by our very good friend Mr. Manish Pandey who is studying in final yr,ECE in RIST. We have also invited two small kids Nishad Mishra(class V) and Mayank Srivastav(class VII) who are very interested in ckt designing and to all of our surprise they have demonstrated their ckt which include glowing LED using human current at their hands, small FM Tx ckt..This really boosted everyones confidence and it has shown that age is no limit if u really want to work...
After lecture session we stated with the cicuit demonstration which I and my frnd Bhupendra Mishra and Sudesh Morey had made for the students. We have made the following projects:
1) Temperature sensor using TMP35 temperature sensor
2) Phototransistor application using MRD300 phototransistor
3) Blinking LED at 2Hz using LM555 timer in astable mode.
4) Operation of NAND gate using IC7400.
5) Matching operation using XOR gater IC 7486.
6) Comparator operation and LED glowing using OPAM LM324.
7) Johnson counter and Ring counter using microcontroller ATMega8L and
codevision AVR.
8) Bulding Multimeter using LM555.
So In this full presentation we tried to make students aware of different functions of generally used componets. We have assumed that this will help them to tackel the problems in the field of electronics and inspire them to work actively in CKT designing..

This group is founded by Mr. Pankaj Agrawal, a B.Tech in Electronics & Communication from Maulana Azad National Institute of Technology,Bhopal. He passed out in june,07 and presently working as research engineer in C-DOT, Banglore.
I have been actively working in this team for two years. We call this team a FearBurster as we feel that most of the engineering students in various colleges has been brought up with a fear of using electronics in practice and more over in product development and this team is working to burst this fear and bring the bright minds in research and development. We have organized a number of workshops in different colleges in Bhopal and working on to extend it on National Level. We have a good experience in working with Microcontroller, FPGAs, networking tool etc. and we are growing as a product development team.
The other members of FearBuster includes:
1) Sandeep Agrawal (Final Yr. ECE, MANIT, Bhopal)
2) Alok Talukdar (Final Yr. MECHANICAL,MANIT,Bhopal)
3) Manish Pandey (Final Yr. ECE, RIST, Bhopal)
4) Sonam Topgay (Third Yr. ECE,MANIT,Bhopal)
