Introduction: The purpose of this Lab is to investigaterd the use of MOSFETS in basic circuits. The MOSFET is used both in the triode region as a voltage controlled resistor and in the saturation region as an amplifier. The first part of the lab you will be viewing the I-V characteristics of MOSFET. Check your measurements with the datasheet and see how they compare. Part 2 is analyzing a MOSFET Amplifier. Using your measurements compare your theoretical and PSpics simulated results. Part 3 involves a Voltage Controlled Amplifier once you’re done setting up the circuit compare your results with PSpice circuit. Part 1: I-V Characteristics of MOSFET Y = mx +b (0.080815 – 0.033466) / (5-3) * m = .0236745 .058017 = .0236745*4 + b b = -.036681 0 = .0236745*x + (-.036681) k’(W/L) =>x intercept = 1.55 Our data from running the circuit simulation is attached on the back, here is the graph we got which looks exactly like what we did in class: Part 2: Analyze a MOSFET Amplifier

### What students are saying

• 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.
