QUESTIONS TO EXPECT
• Difference between built-in voltage and cut-in voltage of diode?
• Why does negative phase margin and gain margin cause instability in a given system? (Explain Qualitatively)
• Under what conditions is Virtual short valid in Opamps?
• Give an Application of positive feedback in Opamps?
• How can one implement PI controller using Opamps?
• How can you generate a perfect 50% duty cycle square wave using 555 timer?
• Difference between harvard and von-nuemann architecture? Why von-neumann architecture is preferred over harvard architecture?
• Why it is preferred to use microcontroller as a sink rather than a source?
• Design a circuit to read temperature from a thermistor, give the input to microcontroller and display temperature (in °C) on LCD?
• Difference between 8-bit and 4-bit mode of LCD interfacing? Why it is preferred to use LCD in 4-bit mode?
• How would you carry out parallel communication between a 5V microcontroller and a 3V3 microcontroller?
* For any difficulties/discussions/query in any question, please leave a mail. (Mail Id’s on Last slide)
QUESTIONS TO EXPECT
• Design a digital system for the following problem statement: A room has an electronically controlled light. If the room is empty, light should be off and if there is someone in the room, light should be on. There is a PIR sensor on the door which provides logic 1 (for few seconds and then goes to logic 0) for a person entering the room.
* For any difficulties/discussions/query in any question, please leave a mail. (Mail Id’s on Last slide)

QUESTIONS TO EXPECT
• Design an electronic system for the following problem statement: the 3 analog signals are A,B and C. Generate 3 digital outputs X, Y, Z based on the following: (Hint: Use OPAMPS as comparators and Logic gates) – If A>C and A>B, Digital outputs X and Y should be high, Z is low.
– If A>C and A<B, Y and Z should be high and X low.
– If A<C and A>B, Y and Z should be high and X low.
– If A<C and A<B, X and Z should be high and Y low.
