Answer: a1 >>RF , the gain Aoo ≅1, which makes Voo ≅ Vio . Thus, all op-amp circuit has some output offset voltage.
2. Determine the voltage gain for the circuit.View Answer
Answer: dF ={1+[RF /( R1 + Rc )]} = 1+[15kΩ/(2.5kΩ+10kΩ)] = 2.2.
3. Where does the compensating network connected in an inverting amplifier.View Answer
Answer: a
4. Why closed loop differential amplifiers are difficult to null?View Answer
Answer: a
5. How to achieve maximum CMRR in the given circuit?1 = RF F = R3 || RC + RB and R1 = R2 1 = R2 and RF = R3 + RC View Answer
Answer: c1 = R2 and RF = R3 + RC .
6. What is the advantage of compensated differential amplifier?View Answer
Answer: d
7. The offset voltage in the voltage follower is balanced usingView Answer
Answer: b
8. Find the maximum possible output offset voltage, which is caused by the input offset voltage Vio =15mv?View Answer
Answer: aoo =[1+(RF /R1 )] =1+(10kΩ/2.5kΩ) = 5.oo =5*15mv = 75mv.
9. Compute the output voltage for voltage follower with offset voltage compensating network?View Answer
Answer: bo = {1+[ RC /( Rb + (Rmax /4))]}*Vin .max =Ra /4 = 20kΩ/4 = 5kΩ.o =[1+(39kΩ/(10kΩ+5kΩ))]*3v = 10.8v.
