  • Q1. Operation of MOSFET.
  • Ans. 

    MOSFET is a type of transistor that operates by controlling the flow of electrons through a semiconductor channel.

    • MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.

    • It has three terminals: gate, source, and drain.

    • The gate terminal controls the flow of current between the source and drain terminals.

    • MOSFETs are commonly used in digital and analog circuits.

    • They can be used as switches or amplifiers.

  • Q2. Operation of FinFet.
  • Ans. 

    FinFET is a type of transistor that has a fin-like structure instead of a planar one.

    • FinFET stands for Fin Field Effect Transistor.

    • It has a thin silicon fin that protrudes from the substrate, which acts as the channel for current flow.

    • The gate wraps around the fin on three sides, providing better control over the flow of current.

    • FinFETs are used in modern microprocessors and memory chips due to their low power consumpt...

  • Answered by AI
  • Q3. Matching Techniques
  • Ans. 

    Matching techniques are used to ensure that two or more components in a circuit have the same electrical characteristics.

    • Matching can be achieved through layout symmetry, device sizing, and current density control.

    • Common matching techniques include resistor matching, capacitor matching, and transistor matching.

    • Matching is important for improving circuit performance and reducing noise.

    • Matching can be done at the device

Interview Preparation Tips

Round: Resume Shortlist
Experience: I had a resume as per the standards laid down by our placement cell. The company did not look at the resume I had with me and it was just a formality.

Round: Test
Experience: The written test had questions on C programming. The topics from C were basically related to pointers, operators and functions. The paper also had questions from Digital Electronics. These were mostly from chips and registers. There was another section for Aptitude also in the test. There were questions from simple electronics as well but I had no idea about them. The duration of the test was around 1 hour.
Tips: For Written test i would recommend ‘C by Yashwant Kanetkar’ and the book by Salle Mahanand for Digital Electronics.

Round: Technical Interview
Experience: The first interview was a technical interview. The whole interview revolved around the concept of Bit wise operator which is a concept in C. They also asked me questions on Digital electronics which were mainly based on the layout of NAND, AND, OR Gates. They were not sure about my proficiency in C so they also asked me to code some simple problems in C. The technical interview lasted pretty long.

Round: HR Interview
Experience: The second round was an HR Interview. It was simply a formality for those who had performed well in the technical interview. They asked me general questions about the talk they had given as well as they enquired about me and my family background.
Tips: The company looks for people who are proficient in C. So, in depth knowledge of the language is needed before the interview.

College Name: SGSITS INDORE
Motivation: For ITTIAM solutions I read about the technology it works in which is embedded software, Smart Phones and Protection of IC. I also consulted my seniors and people who work in ITTIAM solution to get more insight about the company profile.

  • Ans. 

    Questions on array manipulation and logic gates.

    • To reverse an array inplace, swap the first and last elements and continue swapping towards the middle.

    • To implement a -4 input AND gate using 2 input AND gates, use two 2-input AND gates and connect their outputs to a third 2-input AND gate.

  • Q2. -AND gate using multiplexer
  • Ans. 

    AND gate can be implemented using a 2:1 multiplexer.

    • Connect both inputs of the AND gate to the select line of the multiplexer.

    • Connect one input of the multiplexer to 0 and the other input to the second input of the AND gate.

    • The output of the multiplexer is the output of the AND gate.

  • Answered by AI
  • Q3. -calculation of stack space used by a combination of functions and which used for storage of different data types
  • Ans. 

    To calculate stack space used by functions and data types, we need to consider their sizes and memory allocation.

    • Calculate the size of each data type used in the functions

    • Determine the number of variables declared in each function

    • Multiply the size of each variable by the number of times it is declared

    • Add up the total size of all variables in each function

    • Add the sizes of all functions together to get the total stack sp

  • Q4. Threads and processes
  • Q5. Copyfunc(char* source,char* destination,int length) - write a copy function...give test cases
  • Q6. -if you have to AND n inputs,how many AND gates will be required? (I said n-1 and he asked me to prove it mathematically)
  • Ans. 

    To AND n inputs, n-1 AND gates are required.

    • Each input needs to be connected to an AND gate except for the last input which is connected to the output.

    • The output of each AND gate is connected to the input of the next AND gate.

    • This results in n-1 AND gates being required for n inputs.

  • Q7. Func(char a,int bit_postion) - func shud reset the bit at position bit_position in char a and return character
  • Q8. What is stack? Where is it used? (i said function calls) What exactly happens in function calls?
  • Ans. 

    Stack is a data structure used to store and manage function calls.

    • Stack is a LIFO (Last In First Out) data structure.

    • It is used to store function calls, local variables, and return addresses.

    • Pushing onto the stack adds a new element to the top, popping removes the top element.

    • Stack overflow occurs when the stack size exceeds its limit.

    • Example: recursive function calls use the stack to store return addresses and local v

  • Answered by AI
  • Q9. Where do local variables go? Why is stack used for function calls? Can you perform arithmetic operations directly on data stored in stacks?
  • Ans. 

    Local variables go on the stack. Stack is used for function calls due to its LIFO nature. Arithmetic operations can be performed on stack data.

    • Local variables are stored on the stack frame of the function they are declared in.

    • Stack is used for function calls because it allows for easy management of function call frames in a LIFO manner.

    • Arithmetic operations can be performed on data stored in the stack by first popping ...

Round: Test
Experience:
c,dlda,dsp......unsigned characters,function pointers,time and space used by different functions performing the same task and several unconventional things were asked.
:14 shortlisted after apti

Round: Technical Interview
Experience: a few questions to check your creativity(only 30 sec given to solve)viz...convert roman 9(IX) to six.
-mostly he spoke on what should i do......i came across as a very strong person who is very insecured and wants to do everything better than others...he made me realise that its not possible.no one has enough skills for that....enjoy your life.dont sulk and take too much pressure
do something because you like to do it and not for any competition(not even with yourself).
-
Tips: (dos and donts)
-common interview related questions definitely help.find them on internet.
-only c is sufficient but not the marks oriented c that we did in 1st sem.
-a completely different side of c where things we generally dont use or bother about is asked.
like unsigned nos,program stack space,function ptrs,etc.
its very important to clear apti first,which is COMPLETELY different from interviews and definitely more difficult.
do try to think loud during interviews and make them stop you if you r thinking in wrong direction.
-at the end,IT HAS TO BE YOUR DAY
