Frequently Asked Interview Questions: Electronics and VLSI
Here
I am giving you some questions which are asked most frequently in
almost all interviews in the core companies. All these questions are
very basic questions and there are a lot of derivative questions which
generates from these basic questions.
Q.1 What is AND gate? Is it a multiplier or adder?
Q.2 What are digital logic levels? How logic level ‘1’ and logic level ‘0’ is decided in a digital circuit?
Q.3 Design a NAND gate using CMOS circuit?
Q.4 Design a NOR gate using CMOS circuit?
Q.5 What is V-I characteristic is a n-mos transistor?
Q.6 Define cut-off, active and saturation region of a n-MOS transistor?
Q.7 In which domain of MOS characteristic any digital circuit works?
Q.8 In which domain of the MOS characteristic any Analog circuit works?
Q.9 What is threshold voltage of any MOS transistor?
Q.10 What is a latch?
Q.11 What is a flip flop?
Q.12 Why flip flop is a edge triggered device?
Q.13 Make a timing diagram of a latch device?
Q.14 Make a timing diagram of a flip flop device?
Q.15 What is the setup time?
Q.16 What is the hold time?
Q.17 On which parameter setup time depends?
Q.18 On which parameter hold time depends?
