MOSFET IV curves

The goal of this simulation is to build MOSFET iv curves for different values of the MOSFET parameters, compare and analyze them.

1. Make a circuit with a PMOS enhancement mode transistor of your choice and two voltage sources. Do a DC Sweep analysis like we did in the class to obtain the output iv characteristics. Select appropriate range for the sweep voltages. This will be your base simulation showing output iv curves.
2. Starting from the base simulations, one by one, change MOSFET parameters: , and produce four new output characteristics. Each set should have only one parameter changed with respect to the base simulation. Experiment with the size of the parameter change to achieve about 20% change in IV curves (show only the last good result).
3. Analyze the simulation results and describe what happens to iv curves in each case and why.
4. Add a resistor to the output loop and do DC sweep to construct the VTC. Evaluate the gain of the transistor in this circuit by using the obtained graph.

Instructions.

1. Use a transistor from Transistors/TRANSISTORS_VIRTUAL for your simulation.
2. Your submission should include one or two circuit file and one graph file with 6 tabs: one for each set of parameters and additional one for the VTC. Each graph should be clearly marked with the values of parameters in that simulation.
3. This is a PMOS transistor, so be sure you set all voltages and currents correctly with their signs.
