Summary
MOSFETs are a type of transistor used in electronics. Students get practice calculating the current and voltage in circuits with MOSFETs.
MOSFETs in enhancement mode
Enhancement mode MOSFETs are described. Students calculate the drain current for given gate-source voltages. The depletion mode is not considered.
Finding the output voltage
Students use a circuit diagram to find the output voltage for given input voltages. The MOSFET is either on or off.
Describing the output waveform
A square wave input is given. Students describe the output waveform of the circuit. The MOSFETs switch on and off.
References
A textbook is listed as a reference. The textbook is on electronics principles.
