Pre-lab work
- Your lab reports will be drafted using html and placed on CMOSedu.
- Prior to the first day of lab, but no earlier than one week before the lab starts, request a CMOSedu account, using your UNLV email address, from Dr. Baker (rjacobbaker@gmail.com).
- Review the material seen here covering editing webpages (do this before the first lab).
- Read the entire write-up seen below before coming to lab
Experiment 1
Figure 1.21
Hand Calculations
Spice Simulations of Figure 1.21
Scope Waveforms
Comparing my handwork, simulation results, and my experimental results:
| Handwork | Simulations | Experimental |
| Magnitude of Vout | 623 mV | 622 mV | 640 mV |
| Time Delay | -715 µs | -730 µs | -680 µs |
All of my results are similar to each other with less than 10% deviation from each other.
The negative time delay means that the output signal will lag behind the input signal.
Experiment 2
Figure 1.22
Hand Calculations
Spice Simulations of Figure 1.22
Scope Waveforms
Comparing my handwork, simulation results, and my experimental results:
| Handwork | Simulations | Experimental |
| Magnitude of Vout | 693 mV | 703 mV | 740 mV |
| Time Delay | -95 µs | -89 µs | -100 µs |
All of my results are similar to each other with less than 10% deviation from each other.
The negative time delay means that the output signal will lag behind the input signal.
Experiment 3
Figure 1.24
Hand Calculations
We can use this equation to find the time delay because the input signal is a step function.
Spice Simulations of Figure 1.24
Scope Waveforms
For a time delay involving a step voltage we take the time at 50% of the input voltage.
Comparing my handwork, simulation results, and my experimental results:
| Handwork | Simulations | Experimental |
| Time Delay | 700 µs | 736 µs | 660 µs |
All of my results are similar to each other with less than 10% deviation from each other.
Experiment 4
Figure 1.23
Spice Simulations of Figure 1.23
I will take this plot and move the cursor to different values and list them in the table below.
| Frequency | Magnitude | Phase |
| 1 Hz | -171.45 µdB | -360m° |
| 159.78 Hz | -3.02 dB | -45.08° |
| 1 kHz | -16.09 dB | -80.98° |
| 10 kHz | -36.00 dB | -89.09° |
| 100 kHz | -55.96 dB | -89.90° |
I will backup all of my work on my OneDrive and my Desktop.
