Objectives: In this lab I learned about Inverter voltage transfer characteristics, switching voltages, clocks, and gate delays. We did this by first studying the behavior of a single inverter, and then we connected an odd number of inverters in a ring to create a ring oscillator. Design: In Experiment 1 I used a single inverter to represent two logic values as voltage levels. After doing the proper wiring I hooked up two power supplies. One for constant VCC, and one to range from 0V to 5V. I then observed the output as I manipulated the input. For Experiment 2 I created an oscillator ring to learn about clock signals and circuit delays. I built an inverter chain by connecting five inverters and connected it in a loop. I then used an oscilloscope to measure the time period and frequency.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
