Experiment 9: Field-Effect Transistors Introduction: The purpose of this lab report is to inform the lab assistant that I’ve worked through the lab and gained an adequate amount of experience in doing so. The information in this lab deals with field-effect transistors and a CMOS inverter. Objective: The main objective of this lab is to characterize field-effect transistors as well as observe a CMOS inverter. Procedure: First, we connected the FET chip to the breadboard. We then connected a 100kΩ resistor to pin 3 making that our Gate. We then grounded pin 5 and connected a 10kΩ resistor to pin 4, Drain, as well as connecting it to a 5-volt source. Next, we connected a 5-volt source to pin 14 and grounded pin 7. Once this was done, we calculated the voltage drop across the 10kΩ resistor. Second, we made a “depletion”-mode field transistor. We then measured the voltage at the Gate and the Drain inputs as we varied the voltages from -5-volts to 0-volts in .5 increments. We then computed the Drain current.

    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.
