FUTURE COURSE

First of all, we will provide the questions from various IITs, then we will provide the cut offs.
Due to lack of communication factor we will be able to provide questions for only EC(Electronics and Telecommunication)  branch.
We will go in following order,

1. IIT Kanpur
2. IIT Bombay
3. IIT Kharagpur
4. IIT Delhi
5. IIT Guwahati

This is to remind readers that IITM and IITR hadn't conducted interview for EC.

IIT Kanpur

  

Tips for IITK

1. Kanpur interviews are highly mathematical, they generally ask derivations for everything, so be prepared for it.
2. They generally ask questions from basics mathematics, if you fail in this, it gives a bad impression.
3. People interested in VLSI, prepare OP-AMP vary well it is mostly asked question in every IIT.
4. Try to reach there before 8 p.m, hostels are far away from IIT gate, late night you won't get transport medium to hostels (This is not a warning, just a suggestion).
5. Enjoy the scenery, this IIT is full of peacocks.
6. Kanpur calls for only one specific branch, so we are providing questions branch wise.

VLSI & Display Technologies. (Above 200(gen) gate rank were not called for this branch)

1. Draw the Band diagram of PN diode, show its variations with various applied biases.
2. Draw the plot of  x+1/x+sinx.
3. There is always some capacitance between I/P and O/P stage of any ckt. How will you segregate it in terms of I/P and O/P capacitance? Derive the method used.  (Ans: Miller's theorem).
4. Draw the pi model of transistor.
5. Find the value of 'K' and 'm' in y(x) = K(x^m), the value of y was given for various x. plot the function for various values of K and m.
6. Draw the op-amp in inverting config. and write the gain expression. Describe the current flow in this with and without load.
7. Plot I/O characteristics of CMOS inverter.  Describe Noise Margin in it.
8. Can we change an n type semiconductor into p type with same conc. as n type, if yes how, explain?
9. What is condition for oscillation in Hartley and Colpitts oscillators.
10. How does I/O characteristic of PN junction diode shift with increase in temperature and why?
