Question 1)

For the ideal operational amplifier circuit above, which of the following are true?

___________________________________________________________________________

Question 2)

For the difference amplifier circuit above, if R1=R4=1000ohn and Rf=R9=2000ohm, what is the gain, G, of the circuit where v0=G(v2-v1)?

Answer: 2

Question 3)

Consider the inverting differentiator shown above.

If R=2000R=2000Ω and C=0.25C=0.25μF, and Vi(t) = e-2000t V what is the correct expression for Vo(t)Vo(t)?

Question 4 )

The input to the following op amp circuit is vi(t)=10cos(100t). If R=10kΩ and C = 2uF, determine the value of v0 in volts and select the most appropriate answer below.

Question 5)

For the inverting operational amplifier circuit above, if R2=10kΩ and the closed-loop gain is G=−5000, what is the value of R1?

Submit your answer in units of Ohms, while omitting the unit. For example, if your answer is 1000Ω submit 1000.

Answer: 2

Question 6)

For this question, Ra=3kΩ, Rb=12kΩ, Rc=3kΩ, and Rd=12kΩ. va=6V and vb=14V. What is vo? Give your answer in Volts and omit the units from your answer.

Answer: 32

Question 7)

For the circuit shown, Vin=Vin(t) = sin(ωt)and R= 100 .A plot of the output voltage VO(t) is shown.

What is the maximum current in milliamps that can be supplied by the voltage source?

Answer: 5

Question 8)

An opamp is used as a buffer between the source and the load resistor
R in the circuit of question 7 as shown. The opamp must be able to supply at least what magnitude of current to ensure that VO(t) = Vin(t)?

Enter the answer in milliamps.
