Course Name: ANALOG ELECTRONIC CIRCUITS (EE)
Max. Marks: 100 Duration: 3 Hours

PARTA
Answer all questions. Each question carries 5 marks.

1. Draw the de and ac load lines for the transistor circuit. Given Ri=18KQ, Ro=8.2KQ,
Rc=2.2KQ, Vee =20V, Re=2.7KQ.

GND

2. Why does gain of amplifier falls off at low and high frequencies?
List the characteristics of an amplifier that get modified by negative feedback.

4. a) What are the modes in which an op-amp can be operated?
b) An op-amp has a gain bandwidth product of 15 MHz. Determine the bandwidth
of op-amp when Acr =500. Also find maximum value of Act when frequency is
200 KHz.

5. Design an adder circuit to get the output expression as ‏ولا‎ = -[0.1 Vi + V2 + 10 V3]
where ४1, V2 and V3 are the inputs to the Op-amps.

6. What are the limitations of an ideal integrator? Design a circuit which overcome the errors
of ideal integrator.

7. Distinguish between triangular wave and ramp generator using op-amp.

8. Design a phase shift oscillator with a frequency of 100 Hz using op-amp.
