EE 420L Engineering Electronics II Lab - Lab 5
Op-amps III, the op-amp integrator

Pre-lab work

• Watch the video op_amps_III, review op_amps_III.pdf (associated notes), and simulate the circuits in op_amps_III.zip.
• Read the write-up seen below before coming to lab.

---

Again, this lab will utilize the LM324 op-amp (LM324.pdf).

For the following questions and experiments assume VCC+ = +5V and VCC- = 0V.

• Calculate the frequency response of the following circuit. Ensure you show your clear hand calculations.
• What can you neglect to simplify the calculation?
• Does the circuit work if you remove the 100k? Why or why not?
• Does the 100k have much of an effect on the frequency response?
  
• Verify your calculations with experimental results.
• Show, at the unity-gain frequency of the integrator, that the input and the output have the same peak values.
• Is the phase shift between the input and the output what you expect? Why or why not?

• Next, design, simulate, and build a square-wave to triangle wave generation circuit. 
• Assume the input/output frequency is 10 kHz and the output ramp must swing from 1 to 4 V centered around 2.5 V.
• Show all calculations and discuss the trade-offs (capacitor and resistor values, input peak, min, and average, etc.)

Ensure that your html lab report includes your name, the date, and your email address at the beginning of the report (the top of the webpage).
When finished backup your work.
