Lab 8: NMOS Transistors
Experiment 1:
MOS transistors can be used as voltage controlled switches, i.e. they act like a wire when a certain voltage is
applied to the gate and act like an open circuit when a different voltage is applied to the gate.

Diodes are semiconductor devices that only allow current to flow when the voltage drop across the device is
positive. We model diodes as plain wires when they allow current to flow and broken circuits when they
don't. LEDs (light
