Goals and objectives
of the course in terms
of competences and skills
To give knowledge about widely used semiconductor devices, their structure, operation principles, circuit diagrams, current-voltage characteristics and parameters. To develop ability to choose the most appropriate device for the application in question. On the basis of device properties in different circuit diagrams students should be able to choose the necessary circuit diagram and know how to switch the device correctly in the circuit. They must be able to determine whether the device is operational or out of order.
